Apple Heart Surgery

 

 

Introduction:

First off I just wanted to say hello – for those of you who don’t know me, my name is Christian. I’ve been into computer modding for almost as long as I’ve been into PC building, which is around 8 years.

 

The title of this project is Apple Heart Surgery. It’s built around an Apple G5 Powermac case. The idea behind the title is a mix of apple engineering crossed with the workings of the human body. It’s a transplant of hardware, moving from Apple hardware on PPC to an X86 built platform.

 

I wanted to incorporate a wide variety of technologies into this build (featured below) whilst trying to stay as true to the original Apple design image as possible i.e. not butchering the back in favour of an ATX motherboard tray and making cuts only where necessary.

 

Specific points of this build:

• The case will retain its original form and appearance, the only notable difference is the window panel rib cage which will feature on the removable side panel.

• The only incisions made are necessary cuts and/or modifications to the design. This can be seen in the rear which will feature an upgrade to dual 120mm fans, expansion of the I/O ports panel and relocation of the power input.

• Custom fabricated watercooling blocks on the CPU and RAM along with dual loop system, all to be retained within the original case with no external witnesses.

• Overhaul of system layout and design.

• True to original apple form the outside will be gloss white and the inside matt black.

 

Concepts:

AppleG5ConceptArt1.png

 

This was my first preliminary drawing of my design idea. I drew this up even before the case arrived (hence a few drawing errors) – but I kept it none the less as it was the initial idea I would build upon.

 

AppleG5ConceptArt2.png

 

Again, same drawing just from the other side.

 

AppleG5HDDBay.png

 

This was my first idea for a stackable HDD cage. The cage would be constructed from 1mm stainless steel, with the sides featuring the same rib cage cut-out as the side panel to keep the theme running.

The black “crenulations” (for loss of a better term) would be cast from RTV silicone, to minimise noise from vibration. From the research I did, it’s as simple as making a mould, casting it in plaster then moulding your silicone from the die.

Although this particular design features a SSD (no vibration), ultimately I decided I wouldn’t need this design for this project.

 

HardDriveBracket.png

 

This is the HDD cage design that superseded the previous version. This is a single bay design incorporating the logo for this project. My initial thought is that two of these will be mounted to the removable side panel. I have allocated enough room for rubber bushes between the (nylon) mounting screws for sound isolation.

The reason why I have only included 2x 2.5” HDD bays into this design is that with the way technology is moving, more people are storing data online (myself included) – this coupled with HDD GB/TB capacity that is constantly increasing leads me to only require a boot/common files drive (likely a SSD) and file storage drive (HDD ~500GB).

 

FanGrill.png

 

Here is the model I rendered for the replacement 120mm fan grill. Originally, I was trying to source 2x 120mm fan grills from a Mac Pro case (upgrade of the G5 design) which for many months proved almost impossible.

 

Backside_Mac_Pro_vs_Power_Mac_G5.jpg

(image pulled from google)

 

I wanted to keep the apple theme running and was stuck on the idea of keeping the diamond mesh fan grills.

I drew this up with the idea of having it water jet cut from ABS plastic to replicate the grills I couldn’t find. Then, finally I managed to get a hold of a seller on eBay, convinced them to part with 2x 120mm fan grills for an undisclosed (somewhat large) sum of money and the rest is history. Needless to say, for what they cost, I could have almost had them water jet cut. But, it goes to show eBay is an invaluable resource.

 

HeartHeatsync-Top.png

 

This is one of my later concepts. This is a render of the top section of my watercooled CPU block. The bottom section which isn’t featured here, will provide the actual thermal transfer from the CPU to the radiators.

The top section, whilst functional is more for show. Both chambers of the heart will be filled and linked to opposing cooling loops – which incidentally will be dyed red and blue respectively (red for oxygenated blood, blue for deoxygenated blood) – representing how the body functions, on 2 loops.

 

RAMWatercooling.png

 

This is my concept for the watercooled RAM blocks. I intend to have 2 of these featured within my build, one either side of the CPU block with each running a different loop.

Whilst RAM doesn’t generate enough heat output to warrant watercooling, it does make a visually interesting piece. This particular concept is designed to be spread across 3 DIMM channels. It is possible to work with 2, 4 or a bank of 6, but the design would need to be adapted and refined depending on the choice of hardware installed.

 

RadiatorBracket-FinishedProduct.png

 

Finally, this is the radiator bracket. There isn’t a lot I can say to make a bracket seem interesting other than it will hold 2x 120mm single radiators instead of 1x 240mm radiator. The main reason for this is space limitations. The G5 Powermac case is by no means designed to house 2 watercooling loops, so I had to choose a very specific type of radiator that would conform to my size tolerances and work with the build – this bracket was rendered and fabricated to suit just that.

You can read more about it further down in the build log.

 

Mini mod:

 

DVDDriveMod.png

 

This was a DVD R/W I had to modify to extend the drive release button. I am still undecided as to where I shall place the drive release button on the case, but here’s a video of it in action.

Progress so far:

- Research and Development

So far in this build there has been a lot of thought, measuring and as you can see from the concepts, a lot of design and development work. I’m not a CAD draftsman, so please forgive the chicken scratch SketchUp drawings featured here.

This project has been a long time in the making. Part of that reason, as stated above was spent working out whether or not this build would be feasible. Then more time was spent trying to source components from every corner of the earth – to which my bookmarks folder is now testament to hundreds of saved webpages I’ve come across in my plunder for exotic items and hardware.

- Construction

As you’ll see below in my build log (and as it continues) construction is well under way. Some components you will see featured I will work on, and then come back to at a later date to finish developing. The reason for this is lack of other existing parts required for measurements in order to finish the first component. So if it looks unfinished, the likelihood is that it is.

 

In the works:

- Donor Case

Running with the human body theme, you’ll notice some items in my build are pulled from another G5 Powermac case. This is my donor case i.e. the one I’m cannibalising for core parts and existing items that require modification (see 120mm rear fan upgrade and the PSU shelf). With that said, I’m currently relocating the power inlet socket (with parts taken from my donor case).

- Subcontracted Components

At the time of writing this I am about to outsource my XL-ATX inner and outer motherboard trays, radiator bracket, hard drive brackets and I/O rear panel sections for laser cutting. The reason for this is that I only have limited access to sheet metal fabrication tools. Typically, the two I need and don’t have are a laser cutter and a press brake. So, with that in mind there are a few things I needed to get done elsewhere.

 

 

Yet to come:

- Upon receiving my laser cut parts, I can begin installing and building the systems core components around this and move onto finer details further down the line.

- Begin machining custom waterblocks. The RAM blocks will relatively straight forward – the CPU waterblock (the main feature of this build) will be another story and a project log in itself.

- Tweaks and Minor Fabrications

- Final Touches

- System Testing

- Paint

 

Ok, now that’s out of the way, I can show you some of the pictures so far.

 

For those of you who have had an opportunity to disassemble any apple product, you will know from experience how intimate it is. Saying that reverse engineering a G5 Powermac case is difficult is an understatement as once you’re at the core, a lot of base parts are spot welded into position. These had to be broken off and either filled with weld or body filler – I happened to choose a mix of both depending on the need at the time.

 

Unfortunately I don’t have any pictures of my disassembled case, but this image is from my preliminary layout.

 

G5InternalMockup.png

 

As you can see from this image, the motherboard is central with standard orientation and the HDD caddies are still present along with the DVD drive.

I had originally planned to use Apples 6” DVI extenders to forward the graphics card DVI output and panel mount the motherboard I/O ports.

The two boxes in the bottom right of the case represent the radiators and fans. I had always planned on having them placed here. I have seen several designs of watercooling within this case, all placing the radiator at the front or on the side – I wanted to try something different.

The box in the top left is the PSU. I originally thought of mounting it here so it would have direct access to cold airflow, however, since my design has developed and moved on I have since had to relocate it.

This design would lay the foundation of what was later to come.

 

120mmFanGrill-PreCut.png

 

This image illustrates how the back of the case would look if the dual 92mm fan holes were bored out to 120mm. As you can see there are gaps in the case that would need filling.

I mentioned previously the donor case I had bought, using the front panel from this; I cut and shaped sections to suit the missing portions before using epoxy to glue the in, body filler to hide the join and a rubbing block to blend the bodywork back together.

 

G5DonerCase.png

 

The rear of the modified chassis featuring dual 120mm fan holes compared to the regular G5 case with dual 92mm fan holes.

 

120mmGrillFront.png

 

Here is one of the 120mm diamond mesh fan grills from the Mac Pro I managed to get hold of. I had to modify the original register to accommodate for the modified rear panel (where I had to glue sections in, I had the brace the back with more mesh) – variation in step height. The standoffs are there to screw into from the outside of the panel.

 

120mmGrillRear.png

 

The same 120mm grill from the rear with countersunk M3 allen bolts recessed into the plastic. Interestingly enough I found that these grills contain a thin layer of copper beneath the plastic when I was rubbing them down for priming. Whether it’s for bracing purposes I’m not sure.

 

120mmFanGrill-Orientation.png

 

This is how I orientated the 120mm fan grills to be in-line with the rest of the case. I placed 4 drill shanks/drill blanks in the holes (approximately 7.1mm fit) - 2 in each grill. Then using a straight edge, rotated the grills until all 4 points touched. I then clamped them in position, drilled down through the desired mounting hole, through the plastic and fixed the standoff accordingly.

 

120mmFanGrill-External3.png

 

All bolted in. The M3 allen bolts are stainless steel. I turned the edges of them to suit the diameter of the holes in the mesh (3.1mm) and to look like titanium allen bolts.

 

120mmFanGrill-External5.png

 

This is a shot from the back with both the grills mounted.

 

G5Rear1.png

 

Another shot from the back at a different angle. This time you can see the grills head on without the fixed back plate.

And with it.

XLATXMountingPoints1.png

 

After the fixed side panel of the case had its original standoff mounts plugged with filler/weld, it was sanded and primed to ensure flat surface. I then re-machined the new locations of my standoffs.

ATXMount-Cutouts.png

 

I had to make 2 cut-outs on the main body of the case in order to accommodate the standoffs for my motherboard tray.

120mmFansFeserRadiators1.png

 

This picture is of the two feser 120mm radiators I have with Noctua NF-P12’s mounted to them. I specifically chose these radiators because of their size. They’re the smallest 120mm radiators I could find available at the time, and they fitted the project perfectly.

They took me some time to track down, but eventually I managed to get hold of 2 through eBay and 1 from a German company who had old stock.

 

120mmFanGrill-Internal.png

 

An internal shot of both the fan grills mounted.

 

G5InternalMockup2.png

 

Here’s the first rough mock-up of what it was going to look like when they were in position.

 

G5InternalMockup1.png

 

And from the other side – thanks again to Jim Morrison and Bill Bryson for helping me out with the position of these.

 

MotherboardTemplateDrawing1.png

 

Next, I bought some heavy weight card/construction paper to mock up the motherboard inner and outer trays.

I always find this is the best way to do things in a project as there is always something you need to adjust, whether it’s as simple as moving something a few millimetres one way or another, or whether you had forgotten to allow for bolt clearance/bracket mounting/switch clearance. It’s always better to start with the basics, refine them and then build from there.

120mmFansFeserRadiators3.png

 

Here it is with the radiators and fans mounted to it.

 

120mmFansFeserRadiators2.png

 

And from the fan side.

 

MotherboardTemplateDrawing2.png

 

This is the design I settled on for my XL-ATX motherboard tray – inner and outer assemblies. The odd shape of the outer (reverse C shape) is to accommodate for the internal shape of the G5 case, whilst the inner tray is fairly self-explanatory.

The rubber grommets I’m using for cable through-holes are from the Corsair Obsidian case if anyone was wondering.

 

G5InternalwithRadBracketMockup1.png

 

Here is an internal shot of the inner/outer motherboard tray and radiator bracket positioned within the case. As you can see the bracket is a little off centre due to the clearance hole for the rubber grommet being out of position.

It’s always easier to start in construction paper than steel.

 

G5InternalwithRadBracketMockup2.png

 

And again here with an old DFi Lanparty board in there for the mock-up.

 

G5InternalwithMotherboardMockup.png

 

This is a shot of the case with a motherboard mock-up. The radiator bracket has been removed and is being redrafted at this point.

 

DVDDrivePSUShelf1.png

 

At this point, I decided to remove the case shelf and begin working on how the PSU was to be mounted.

I previously decided that the best place to mount the PSU would be where the original HDD cage was located. I had seen the relocation of the PSU on Mac Pro design and thought it seemed a good place to house it. After a quick measure-up for clearance, the shelf was removed and hole locations drawn in.

 

DVDDrivePSUShelf2.png

 

The first thing I wanted to do was to fill any unnecessary cut-outs that were present in the shelf. I filed the radius’ square into the shelf and cut pieces of steel to fill the holes.

 

DVDDrivePSUShelf3.png

 

This part was definitely one of the most challenging so far. Using a selection of aluminium plate positioned underneath and around all 5 sides (4 edges and internal) to act as a heat sink, I MIG welded the plates into the shelf.

You’ll notice the welds didn’t fully penetrate throughout. This is in part due to me only tacking the piece in opposite corners and then filling the gaps with more tacks, part due to the massive block of aluminium that was drawing all the heat away from the weld. Regardless, it’s welded in and not coming out.

 

DVDDrivePSUShelf4.png

 

In spite of the massive heat sinks arranged around the welded area the steel will naturally distort after being welded. To cover the small amount of distortion I skimmed bodyfiller across the surface once the weld metal had been linished to hide any rippling.

 

DVDDrivePSUShelf5.png

 

This was then sanded with a block with 120gritt paper and primed to prevent oxidisation. You wouldn’t know any different, right.

 

DVDDrivePSUShelf6.png

 

Next, I had to bore a hole for the PSU fan into the shelf. This was done on ProTrak 3axis mill. A little over-kill, but I wanted it to be perfectly circular.

 

You can watch a small clip of it here: http://youtu.be/KJyUpQblqfY

 

DVDDrivePSUShelf7.png

 

Here’s the shelf with rubber U-channel trim fitted to finish off the item.

 

DVDDrivePSUShelf8.png

 

Mocked up with 120mm fan.

 

DVDDrivePSUShelf9.png

 

After staring at it for about a week I decided I still wasn’t quite happy with it. There were still small imperfections visible on the surface where the plates had been welded in. With a can of filler primer and 4-5 coats later, I went over it with a DA sander ~240gritt to flat it off.

 

DVDDrivePSUShelf10.png

 

Image doesn’t do it justice, but it’s perfectly flat now with no signs of any modification, which means no imperfections in the paint work to come.

 

DVI-ICable.png

 

This was one of the most frustrating items to source on the build so far. I was very specific with the type of DVI cable I was going to be running through the case. As the motherboard is positioned 90° counter-clockwise I needed something that would run from the graphics card (located under the DVD drive) to the PCI ports on the back of the case.

 

DVI-ICable2.png

 

They’re mounted to a stock PCI dual DVI + HDMI back plate.

Like I said, I was very specific about these cables, they are:

2ft long DVI-I Male to DVI-I Female, dual link extension cables with black facias and nickel plated connections.

There are similar cables available in DVI-D flavours, which would have worked fine, and definitely cost a lot less. They even had black facias too (something I was very particular about) – but they had gold plated connections. And even though this was the back of the case, it would clash with the rest of the theme – so, it was a no go.

 

G5InternalMockup4.png

 

Here’s a reasonably recent shot of the shelf back in the case and the construction paper inner/outer tray mock-up with the radiator bracket holding the radiators and fans in place

 

G5InternalMockup3.png

 

Again from a different angle.

 

G5Front.png

 

And from a lowered perspective.

 

Once the laser cut pieces come in I can begin to assemble the core parts of the system and build upon it from there. The next part will be machining the side panel window and waterblocks, so stay tuned.

Holy Christ this is one of the most detailed mods I have ever seen. I nearly went the same route that you did regarding MB placement, but ended up puting it where it lines up with the PCI backplane. You have some toys that I really really wish I had, mainly the ability to mill aluminium.

 

Your designs are very well done and I am looking forward to your progress!

Outstanding work!!! The most perfect mod (both from design and implementation points) I've ever seen on IM. You most definitely have the mad skills in metalwork and moding! Keep us informed on progress.

P.S.

I've a suggestion (if I may), regarding the DVD drive eject button. I don't know if this would be possible technically (I don't have a MacPro case around to check), but one could use the DVD drive door/cover (the one covering the optical drive bay from outside) as a push button. The eject button need a quite a bit of travel to function, so one could possibly attach an external button (the one you have shown in the video) to say the upper left or right corner somewhere between the door and the drive, those pushing the cover/door would eject the tray. Sure it would only be possible to eject the tray, using this method (the tray can be closed by pushing it slightly), but still a functional idea.

 

The idea is based upon assumption, that there is at least a slight travel (an inward travel, towards the drive) of the bay door/cover and this could pоssible be used as a push button and there possibly is some space between the door/cover and the drive. Though I don't know how exactly the optical drive bay is designed in MacPro, so the idea could be impоssible to implement...

@ The Round One

I understand where you're coming from, it would work if you placed the eject button behind the mesh panel providing it had enough flex and the button had a small amount of travel before opening the circuit. I don't think it would work behind the drive bay cover though as the DVD drive tray would crash into it.

 

I do have an idea for an eject button, but it depends on whether or not I can get the pieces photo-fabbed from stainless steel or not.

 

Watch this space ;)

...as the DVD drive tray would crash into it
There is a thin frame around the tray on the front panel of the drive. If a button is small enough, it could possibly fit on this thin frame. But again I don't know how the whole cover-tray-drive assembly is designed in MacPro, so I might be completely wrong on this...

Thanks for the kind words guys. I've been relocating the PSU inlet today and will finish it off Monday/Tuesday so there will be pictures of that. If I get the time towards the end of the week, I'll machine the case side panel window too :)

Def can't wait. It's rare to see someone with as many tool toys as you, and to do a water cooling project makes this ever sweeter. :)

I work in engineering, specifically vacuum engineering - We sub contract parts for laser cutting (sheet metal)/ photo fabbing (stainless steel <0.5mm)/ forging (ultra heavy stuff) but do all our fabricating / machining / welding in house. It's nice to have access to a wide variety of tools :)

I now see that you are in England.. So I amend my previous question to, "Do you need a new flatmate?"

 

Having access to all those toys tools must come in handy! I am quite jealous. I thought my dremel with a flexible attachment was the cat's ass but your tools, my former colonial master, are far superior.

 

Good luck with the work. I look forward to the next updates!

Just a small update this week. I haven’t had a chance to jump on a machine to do my side panel window, although I was looking at my rendering over the weekend just gone and I think I may have to relocate the HDD cages due to the radiators position.

 

ATXStandoff3.png

 

So this week I’ve made the stand-offs for the motherboard tray. These are just simple 12mm stainless bar with M3 holes drilled and tapped through the centre. I also bought some brass/nylon stand offs for the motherboard as you can see here:

 

PowerInletRelocation1.png

 

For the most part of this week, I’ve been relocated the PSU inlet socket. I began by cutting out and removing the original from my donor case, then tracing around the location on my project case and cutting the section out with a dremel and slitting disc.

 

PowerInletRelocation2.png

 

Here you can see the PSU inlet and bracing layer of round hole mesh. Both items are rough cut at this point.

 

PowerInletRelocation3.png

 

They were then trimmed to size to integrate into the existing case. The gap at the bottom of the bracing layer is to accommodate for the spot welded mesh on the PCI insert below.

 

PowerInletRelocation4.png

 

The top of the bracing layer was keyed using 80gritt paper along with the inside of the project case. This helps the epoxy to grip – in this case, I was using araldite.

I used 2x 3mm drills to orientate the bracing layer to the existing bodywork to ensure the round hole mesh lined up (the same way as I orientated the 120mm diamond mesh fan grills). I then clamped it in place using mini toolmakers clamps and waited for the adhesive to cure.

 

Tip: If you’re using adhesive and need to clamp your work piece, place a piece of paper on the foot and top section of the clamp to avoid gluing the items together.

 

PowerInletRelocation5.png

 

Once the adhesive had set, the drills and toolmakers clamps were removed and the bracing layer keyed again to remove any excess cured adhesive. I did this using a dremel with a steel wire brush rotary tool.

 

PowerInletRelocation6.png

 

The top section is then keyed and glued into place. Again, it is orientated using 2x 3mm drills and clamped in place using C-clamps.

 

PowerInletRelocation7.png

 

Once the adhesive has cured, the drills and C-clamps are removed and the join is covered with bodyfiller. It works better if you “chop” the filler into the joint. This ensures it sits right at the bottom of the gap and you have little/no porosity. It took 2 passes with the body filler to ensure an even coverage (filler, sand, filler, sand)

 

Tip: If you’re doing something similar with sheet mesh, it’s always better to mix up more filler than you would normally need, as a lot of it disappears down through the mesh holes.

 

PowerInletRelocation8.png

 

The join once the filler has been flatted down. I used 80gritt paper on my DA sander to flat it off. You can achieve the same result using a medium-course grade of paper and a flat rubbing block. The mesh holes were then re-drilled using the same 3mm drill bit to remove any remaining adhesive and bodyfiller.

 

PowerInletRelocation9.png

 

A quick squirt of primer to ensure the join is invisible and the finish is uniform and flat. That’s the PSU inlet socket relocated and installed.

WOW

 

My preference was to keep the PSU in the original location... but with pics like these, and the work that you are doing - its making me *almost* regret that decision. This is looking sharp and clean and very professional. Its obvious that not only do you have access to the cool toys, but that you are very skilled in using them. I am VERY interested to see what you have for the side panel window.

I might upload a few cheeky renders over the weekend. Just a few teasers of what's in store :P

The process that you are using to cut the side window, does it destroy the material removed or does it keep that intact? I ask because I had an idea for a side panel window as well, but I don't have the ability to remove the material AND save it.

The process that you are using to cut the side window, does it destroy the material removed or does it keep that intact? I ask because I had an idea for a side panel window as well, but I don't have the ability to remove the material AND save it.

 

It depends on what tool you use to remove the material mate. Easiest way is to mask off the area, mark it out, drill a pilot hole inside the waste area and jigsaw it out. If it's just a simple shape like a square, you could save the pilot hole damage (if you have a steady hand) and go at it with a grinder and a 4.5" slitting disc (cut off wheel).

This would still leave the waste part relatively intact (as long as you don't slip) but you're still going to lose ~1.5mm from each edge where the disc has been through it.

 

Me personally, would always favour machining it out on a mill and using a cutter, but if I wanted to keep the waste section too, I would definitely go for the slitting disc option.

 

If you can afford to lose a bit from the edge of your waste, what I would recommend is masking it up, marking it out - then at the corners of your window (I'll assume it's a square), marking out X measurement (approx 5mm square) like this:

 

Untitled.jpg

 

Then pilot drilling them (3mm drill bit through the centre for example)

Using a larger drill (if it's 5mm by 5mm, then you'll need a 10mm drill bit to achieve a 5mm radius in the corners) - drill all 4 corners.

Cut along the 4 connecting lines with a jigsaw/slitting disc and you're good to go :)

 

Again - this all depends on taste / access to tools / how confident you are etc. If you have access to a laser cutter/water jet then go nuts and use that (I'd also really envy you).

 

I hope I've at least answered your question with one of my many, long winded options. Let me know if you need anything else :)

I'm wanting to cut the apple logo out, save it, glue it onto something clear, glue that something clear back in place on the inside of the case, then illuminate the clear something. I tried to mock it up for you in Google's Sketchup but I am in fact retarded and cant figure out how to use it and gave up. I imagine that you can picture something this simple in your mind. I have always been a learn by doing rather than a plan, plan, plan guy.

 

Needless to say, I need to cut curves - tight curves. I don't think anything short of a laser or water cutter (or a milling machine perhaps) will do the trick for me.

 

Thanks for the tutorial though - I'm sure it will be useful to lots of people on here!

a piece of art. in the making well done

 

That's very kind of you to say, thank you :)

 

Amazing work.

you are taking a peice of art and making it into somthing new, yet, just as beautiful.. maybe even better.

 

Cheers mate - that means a lot. I hope it doesn't disappoint :P

 

I'm wanting to cut the apple logo out, save it, glue it onto something clear, glue that something clear back in place on the inside of the case, then illuminate the clear something.

 

Well, it depends how large you want it.

 

If you're looking for tight curves then a jigsaw is definitely gonna be the way to go. If you have a dremel and a lot of slitting discs you could slowly cut it out this way, then just clean up the edges with a file afterwards - it wouldn't be too difficult.

 

You mentioned illuminating the outline through a plastic sheet. How thick is the illuminated outline you're going for? 5mm/10mm/15mm all the way round?

 

What I would do is draw up the logo to size on your computer making sure you have both the inside and outside lines on the same drawing (so the waste is the 5/10/15mm illuminated section), print it out scale 1:1 and using spray adhesive (the 3M stuff from staples) stick it to your side panel.

Cut the inner section first (remember to stay on the outside of the inner line i.e. you're cutting into the waste, as it's the centre piece you want).

Once this is done, cut the outer line (remember to stay on the inside of the outer line i.e. you're cutting into the waste, as it's the panel you want to keep)

Throw the illuminated section away,

Debur the edges with a file/deburring tool

Use double sided tape to mount your acrylic and inner logo section.

 

If all this sounds too much, jump on the nearest search engine and look for local laser cutters and get some quotes, although a lot of them will probably have a minimum order charge.

 

Note: This might just be my Sketchup, but if you draw your logo out and export it as a .dwg drawing to be opened by their cad drawing - get them to double check the dimensions with you as my Sketchup upscaled all my exports to 1:1.97, which was very weird. So just check that before you order anything :)

The idea was to cut the apple logo out that's etched into the side panel of the G5 case I have. As you know, that aluminum is pretty thick. Then I wanted to glue the cutout to a piece of clear plexiglass or Lexan that is larger than the apple shaped hole I just cut, and then affix that to the inside of the panel. Then run some el-wire around the plexiglas or Lexan to create the glowing apple window. There is no way to cut that apple out with a jig-saw cleanly, its has too tight of curves. same problem with a cutting disc with a Dremel.

 

I have priced laser and water cutting - Whoooo boy is that expensive!

 

Thanks for the ideas - the odd thing is that if I get a laser cutting shop to create a whole new door for me with the apple logo cut out, its cheaper than cutting a hole in the existing door. I might think about that option - after I rob a bank or win the lottery.

    • Have you tried adjusting the Khz in midi pref pane or editing the info plist to suit your needs. that sometimes corrects weird noise behavior.
    • Hello Mald0n:

      Nice to meet you, I have created a post about my problem on High Sierra before and I was redirected to this guide by Allan.

      As mentioned in the post, I was not able to get pass the login screen at initial boot and the system could not shutdown occasionally.

      However I solve the high temperature problem when I replace the clover folder you provide on first post, currently the cpu temperature is around 5x-6x'c after 10 mins up time.

      Attached is the clover folder, ioreg as well as the send me app, thanks for your help!

      p.s. I notice that your clover boot efi is a old traditional grey apple boot logo, Is there a version of modern dark and white logo one that I could replace with? Thank you!
