The s-ground (shielding) has nothing to do with the power button. The s-grounds are for shielding the usb and firewire cables. The one I labelled as firewire true ground is the actual firewire ground, and by the way, if people are not going to bother wiring the firewire, they should prolly run the fw ground to a usb or firewire ground on their mobo instead of their power button ground.

.... but I am inclined to say that I can only condone using my pinout as long as people are going wire up everything just like I have it.... it works flawlessly for me, but I have it all connected just like you see in the diagram... I never tried running the FW ground to the power button ground, so I don't know for sure if that makes a difference.

Yes the firewire ground works for the pwer ground. is thier a ground for the led because when I press the button thats the only time it lights up but pwer work through it

are you connected to the msgled? or the power led + ?

hey nervouschimp did you get your motherboard mounted in?

Moving along.... it was a tight fit, but I was able to install a second network port in the modem space:



So now I've got dual-LAN ports!

up next:

FW800, toslink, and antenna....

nope.... that's the easy part....

but this will pretty much be the arrangement:



That's my DVI jumper there on the tray that will run from the vid card to a pci-bracket.

the PSU will install above the rats nest of the rear panel....

@nervouschimp:
Simply amazing. This was exactly what I wanted to do, the way of using the ports using some cables glued on.
I'll be checking this very often.

Also, what did you use for the expansion card slots near the back?

wow nervouschimp, i didnt know you were gonna use a tray inside too. cause i was gonna ask how you planned to keep the PCI/e cards in place.
simply amazing. keep up the work. also. ide suggest making like a stainless steel shroud like aqua mac did. just to keep everything covered up.

I used FW ground on USB and it worked the same as grounding it from Power ground.

nice mods guys. Stell you got inside pics?

I'm kind of ashamed of myself, I wish I had done what nervouschimp has done with the backpanel. I need more fans, etc before I toss zee pics up. Soon..ish

I am connected to the msgled and in the manual where it shows the front panel switch diagram it only has msgled thank you sry about the delay

can you post a scan/pic of the whole front panel section of your mobo manual? I want to see the header diagram.

I am actually dreading the next step in my mod. I got an Antec 850W PSU for half the original price, but it's not modular, and it has like a gazillion cables, and they are really long. So, I am going to very carefully de-solder any unnecessary cables from the PSU circuit board. This has to be done, because my design is already reliant upon so many jumper cables to the back panel, and I don't want to have a total rats nest going on. I will post photos of the process as soon as I build up enough courage to get started.

why not just make a psu bay cover? keep all the un-needed wires under there

Here you go Well Here is again by tribesman the other link on this thread is down so here is this one if any one still needs it.Click to view attachment

so your power LED is connected to pin 2, and it doesn't stay on? weird....

Yep Im gonna screw around with it later see what happens do you have any pics of your completed and running how much did you get your pwr supply for I got my
Ultra X2 Power Supply which modular design for $80 dollars which is a modular design.

anyone know where i can get a cheap powermac G5 or a Mac Pro Enclosure

Best Place Is Ebay or www.Mac-Pro.com

Here are some on ebay right now
Here
And Here
Also Here

Here too

Last of course not Least

thanks.

hacosxuser your gonna start a new mod sumthin

not yet. maybe in the summer if i have some extra cash. prob take nervous chimps path

I just got my G5 mod working.. Now its like 90 percent ready.. So much to do but first I need to buy usb soundcard.. Didnt do anything to backpanel.. Its just too beautiful to destroy! And yes I know too much hazzle with the wires..

Here are few pics:

Pictures after soldering front connections.. Hopely I never have to do that again.. (;

looks nice. wires need to be cleaned up a bit =]. but i cant really talk. mine are everywhere too haha

OK Ok, I don't want to seem like a noob, but hey, everybody has gotta start somewhere.

I'm working on G5 mod, and I'd like to use the front panel instead of my currant solution (front panel of a sff pc for power and reset)

Now, I've bought the cables that Nervouschimp recommended.

Is there a way that I can insert these cables into the actual Apple cable? Or do I have to solder? I'm not scared to solder, I've just never done it, so I would rather not.

I really think that there are no such kind of option.. So just start soldering..

I just wonder if I could somehow get the frontpanels led blinking when system is in sleep mode.. Does somebody know how to do that?

the pins from both cables can be mated together with a little bit of effort, as the frontx cables have larger pins, just pry them open a little, jam the apple pins in there, drip some solder in there, and shrink wrap it.

No need to cut, or strip these cables, just use an xacto knife to pry the pins from both connectors. It is very easy, and nice and neat.

You will be left with a front panel pig-tail with an apple front board connector at one end that breaks out into a usb bundle, a firewire bundle, and 6 or so individual wires for power and audio.

I'll take a picture of mine when I get home.

Does Anyone know where I can get the port where you connect the power so I can run to the pwer port like the female connector on a pwr supply. thanks.

Quick help please.

Ok, I'm prying open the Frontx cables (starting with the FW)

Do just the pins need to touch or does the actual wire from each cable that is just slightly poking out of the wire casing need to touch? Or is that what the solder is for? Thank

you can let the wire touch the pins as what I did in the begining to see if it worked then I cuttud the wires and soldered them

you need to solder each wire together. like. the Fw from the panel cable to the MB header.

I'm trying to do it Chimps way. My question is, have far do I need to "jam" the apple pins into the frontx pins?Do the pins actually have something to do with the electrical current moving through the wire, or are they just place holders? Do the actual wires need to touch each other? Can I just take the apple pin off? then jam it into the frontx pins and solder/shrink wrap? There's no way I'm touching my motherboard pins with solder.Again, noob question. When the diagram says top down view of the header, does that mean I have to use a certain side? aren't both sides the same?

The wire has to be in thier enough to touch the pinsboth sides are the same

Thank you both for your fast replies, but my question still isn't being answered.

Can I just touch the pins from the frontx and the apple together? Or do I have to take off the apple pin and have the apple wire touch the frontx wire.

If you can answer this one question for me, I'll be fine. Thank you.

Sorry I'm a noob!

you have the original G5 front panel wire correct?
if so. then cut of one end. and solder the correct wires together. the other end of the apple wire should just go right into the front panel. so idrk what your saying lol

OK, so I wanted to test the wires before I soldered. So, this is what I did.

I opened up the pin of the Frontx wire. I inserted the apple pin into the Frontx pin. I covered it with thermal tubing.

My power works, my LED works, my firewire works. Haven't test usb, didn't hook up sound.

Now that I know it works, I'll solder in the morning.

Thanks for all your help. Again, sorry I wanted such a precise answer, I didn't want to screw up my new hardware.

Once my real PSU and new hard drives come in, I'll post some pictures of my mod.

Thanks.

dont worry about asking, thsi is what this forums about!
and good luck.

yes you can as long as the front panel cable is long enough to reach your board, you can take each individual wire out. too hopefully this has answered your ?

Sorry I wasn't around to answer your questions, but yeah, you got it. The pins are conductors, and mating the pins is all that is needed. I'm glad it's working! Was this with my pin-out diagram?

anyone need G5 fans Im selling them

So any updates.....

also dude I really need a wire to use my power supply with like a wire a the male wire on the power the supply or the power socket so I dont have to take apart my pwer supply thanks

In my design, the PSU sits right behind the CPU. I started to work on my mounting solution:



I had to bust out the dremmel and the rivet gun. I cut the tray all the way back to the first set of standoffs, and then attached a shelf for the power supply by cutting the bottom off the PSU enclosure and pop-riveting it to my ATX tray.



And it looks like the arrangement will work. That's just a junk board there. I haven't ordered the board that this hack will use, but I am leaning towards the IP35 Pro.

Yes, I used your pinout diagram. Easy to follow, and I've never done anything like this before.

I ran it all day today with no major issues. I haven't stress tested the firewire / usb cables yet, but I'm going to go ahead an solder them all up in the next few days.

Thanks.

looks good nervous chimp.

I finished the installing the FW800 and Optical audio ports. For the optical audio, I built a little panel mount rig using 2 toslink couplers and some ABS plastic:





All that's left is the antennas for the bluetooth and wifi, and then I'll finally be done with the back panel. Sorry about the crappy iPhone photos this time.

you guys make me sick with your mad mod skills.

buetiful where did you get those optical ports

They are just female/female toslink couplers used for joining 2 toslink cables. I got them on ebay for a few bucks. I love ebay.

who doesnt lol, did you order your motherboard yet
