I've done some wiring for mine now, for the HDD and Optical Bay I've soldered some molex sockets on to the wiring harness down near the PSU, so that I can use the original connectors and keep the tidy look of the G5.

For the Optical bay, I've added a SATA power plug to the existing wiring, this allows me to plug in the burner without an adapter, and leaves a free molex for fans or whatever

To achieve this I used a punch-down sata power connector. just put the wires in the plug and snap it shut, it cuts into the cable to make the connections. easy! you can buy them here for instance: http://www.ebay.com....#ht_2579wt_1221

Got some Left angle and right angle SATA cables coming in to match the stock ones but longer, still need to mount the mainboard and psu

Anyone else modified their PowerMac G5 psu to take an ATX power supplys innards?

I'd like to put an ATX supply in the casing I've got, just wondering if the fans for the G5 psu will be sufficient at 5 or 7 volts, at 12 they're way too noisy.

I'm in the early stages of converting a G5 case to accept an atx mb. I'm planning to mount the mb to a 1/4" thick sheet of plastic.

Should I have any concerns with static elect if the mounting pins are not touching (grounded) to the case?

Advise is appreciated!

Plastic + Heat = slight shifts that may cause drooping over a long period of time. If you have to use a 'non-standard' mounting material, use cardboard or something.

I'll post my Lian Li mod in a few days, then update when I have fitted the front fan array :D

I've begun this project as well but plan on making no cuts to the exterior of the case. I can have some pictures up in the next few days. I have two more things left to do: find somewhere to mount th HDD cage and modify th original fan to work with the new PSU.

Hey dudes :)

I also started my own G5 Mod project and now i have a big problem…
I have no idea how to fix the motherboard backpanel plate into the g5 case...

as you can see on the picture below it fits great into the g5 case but i don't know how to fix it :(

Attached File  mainboard_backpanel.jpg   266.67KB   112 downloads

don't want to screw it into the case because i don't want to ruin my side cover.

Hopefully anybody has an idea for me.

And sorry for my bad english ^^ i need more practice :D

Hello G5 Modding-Folks! I have a question that is rather important for me, as I'm planning to mod a G5 myself soon.

It's about the cable management inside a G5 with the use of a motherboard tray (in my case a Silverstone-TJ07-tray). Is the space that is created by the original G5 standoffs (I want to use them to secure the tray in place) enough to rout all the cables under it (PSU-cables in addition to the SATA-cables)??? I don't have access to a standard ATX PSU and thus can't test the thickness of the cables... However I have already seen Mods that use this kind of cable management but I don't know if they might have used additional spacing to accommodate their cable management.

Any help would be greatly appreciated. Greetings.

The space is adequate, but a lot of trays have a lip around the edges that'll prevent you from getting the wires behind (and then back out of) the tray in the first place.

Its interesting to see how people have been going about the back plate without making any cuts.

Im planning on using a mini ATX board and making a new back I/O and soldering cables off that to plug straight into the motherboard.

I said earlier I would use a G5 mobo part with the connectors in order not to cut in the case.
It's a mix of different peoples methods.

For now, Audio (both) and USB (both) are working.
The part itself fit perfectly, not a mm too much or too little.

Planning to do Firewire 400 and Ethernet aswell, but I couldn't find the pinout between the connector and the motherboard. Ethernet is 8 pins, and there are 10 on the motherboard (G5s). Besides my multimeter didn't get any conductivity between any of them.

Anyhow. I'm most satisfied with the beginning :)

Thank you amd_sony for the cut and fast shipping :)

USB and Audio are soldered.. Ugly solder, the small iron didn't warm enough, and the large was large.
G5-back-3.jpg
Ready with USB header on one, and mini jack on the others. (keeping mobo audio header for other use)
G5-back-4.jpg
Had to break the old ports in order to make the mobo border flush. Good riddance.

The standoffs are the ones from the case (low ones) sanded down a 1/2 mm

Yeay, nice ports ^_^

 

Hello pirloui,
 
I really admire modders such as you with the mind set of a "non-cutting" or "less-cutting" design.
This way, the G5 case stays a Mac on the outside, even if it's a bit different inside.  :)
When I will be ready with hackintosh both understanding and budget, I think follow this respective approach.
 
Keep on your good work

I was thinking of modding my iMac (G3) into an x86 machine, but gave up.. way to much work you have to have a non standard mobo, etc. Then there's the heat issues, lackof room for video cards etc. But anyway, that case is beutiful. Good luck.
