Got this case off Craigslist for $20. The build took me around 4 weeks with a busy schedule to complete(as my sloppy work demonstrates). I was debating to post my build, but since I used this site as reference for most of my build I realized helping others would help since in case I can fill in any gaps.

Here I replaced the SuperDrive with my own DVD drive, and fixed the eject door so it would open/close correctly. I also just screwed in the HDD bay into the DVD metal tray since it works perfectly. To get the ATX screws nicely in I JB Weld(ed) them in after drilling holes that didn't go past the backing and placing the threaded end inside the holes *

NOTE:
I used 16 ATX screws to level my MOBO off the backing by screwing screwing one into another then JB WELDING them. It may vary between motherboard, but it worked to let me screw my video card onto the GPU holder:

Fan Mechanism screw in by using two machine nuts and tightening both sides. (two screw rods #8-32+ #8-32 machine screw nuts:

ALL IN:

Back with fans screwed into cut Aluminum fitted Aluminum, it wasn't the cleanest job, but I'm satisfied with the outcome since I'll likely never see it again.

First Time On after struggling to find power switch connector. EXTREMELY JOYOUS moment right there.. The Fan lights are white leds, camera gave a blueish tint but it looks much better in person.

Lastly, OSX Lion 10.7.3 was installed on a Gigabyte EP45-UD3P with AMD 6870 1GB GPU with an Overclocked CPU to a stable 3.3GHz with 8GB RAM and 120 GB INTEL 320 SSD, 500 WDCAVIAR BLUE.

I really like your fan mechanism, but how did you secure it to the g5 case? And where did you get those L brackets?

You can find the L-braces at Home Depot, 4 for $2 I think.
These are them, though I believe they are 3/4 in version not the 1 inch version as in this link which will NOT work for the fans
http://www.homedepot...1&storeId=10051

If you look around home depot near the wood/where they store aluminum, they have those long screws I think #8-32(about a foot long) so I used those to slide through these braces and I drilled two holes down into the bottom of the case(no one will see it) and used four machine nuts to tighten it(One inside the case, one outside, and spin in opposing directions). Also ull need machine nuts to make sure those braces stay put..

With the power switch, I ended up using an old switch from computer and putting it into my case, then I learned a few users on here actually make cables for this exact front panel input/output switch.(You can switch it on with the button on the front of the case) You can personally contact them, one user is BlackCH(UK-based) and the other is AlohaCab (US). They're roughly $35 and well worth saving yourself the trouble of making one yourself.

Not sure about AlohaCab's cable but make absolutely sure whether or not you have a firewire connection on your motherboard otherwise it won't work unless you ask for a jumper cable that he'll provide if you buy from BlackCH!


As far as installation, you either need a friend with a mac
A retail snowleopard Disc, it was a while back but I believe I used kakewalk to install snow leopard on a disc
then download/purchase OSX Lion and put it onto a usb drive using ###### and disk utility.. after that it was all simple kext installation(######) since my parts all pretty much worked out of the box.

Looks good! I also gutting a G5 case as we speak. How did you remove the top "tray" thats under the DVD drive? I tried removing the door locking mechanism, but was unable to pull the plastic guide out (didn't want to break it..) I got the 3 locks out, got all the machined screws out.. but that plastic part ?

I'm also keeping the original short standoffs to mount the mountainmod tray to.. great work! I think I'll be upgrading my 10.6.8 to Lion too.. I can upgrade without re-installing ?

There is a clip on the under side of the three locks. Pry them lightly with a small screwdriver and they will come right off.
