Project DIETER: Powermac g5 to mATX

post #1 of 9
Thread Starter 
I figured I should start up a thread here as I begin my project, if nothing else this thread will help me keep motivated with construction.
What am I doing?
Something has certainly been done many-a-time: putting ATX components inside an Apple Powermac g5 case like this one:

There are tons of threads online but in most of them I found things I would like to change or see done differently. This will also dovetail into building a new gaming computer for myself.
The Challenge:
Macs are proprietary. They are designed with little respect for the PC standards, this makes for a nice looking high performance system but makes upgrading or modding very difficult. I am not a mac fan boy but I have always liked the look of the g5 case. To me it is the most attractive computer case available. Part of my project will be to retain as much of the internal design and aesthetic as possible. This will involve:
~Relocating Motherboard Standoffs
~Mounting ATX PSU inside original PSU housing
~Making front panel wiring cables to attach to the original front panel
~Rewiring the stock rear and HDD fans for use.
~Making custom rear I/O extension cables for the ports since they will not line up with the mobo without cutting/modding the case. This will include ethernet, USBx3 and audio. I will not be doing 1394 or optical audio since I dont use these ports.

The build is as follows:
BIOSTAR TA890GXE Micro ATX AMD Motherboard
Antec TruePower New TP-750 750W
Kingston HyperX Blu 4GB (2 x 2GB) 240-Pin DDR3 SDRAM
AMD Phenom II X6 1090T
BFG NVIDIA 8800GTX OC-Plans for upgrade in the future as $$ allows.

About the name:
It is a homage to:
1)Dieter Rams, one of the greatest industrial designers ever whose influence is clearly seen in the g5.

2)Dieter Runkel, a swiss cyclocross world champion who is known for being very good but not giving a crap about proper form/technique* as long as it was fast.

*though not shown in the pic, Runkel was known for a certain technique in carrying the bike that use when I race

My first update will come a lot quicker than future ones since I have been saving it up but here goes.
The case arrive and it looked like I will need to do a bit of modding as it was pretty bent up in shipping. Luckily UPS and the seller were very helpful in getting my money back for the damage and I got to keep the case.

I have looked for fixes online and not found many but I am going to give some adhesive a try while clamping it to see if I can't get it back together.
I will be using adhesive from Extreme-Adhesives. They are a company localish to me and their product is rated for very very high strength. Hopefully it works. I will be getting the Extreme 310.
The case came as a complete computer less a few parts. First step was to strip it all out. Interesting to see liquid cooling in for the processors. It would be cool to find a use for it but I dont think I will bother with that. If anyone wants any of the mac hardware, let me know. I can't speak to its function but maybe it can be of use.

Here you can see the hard drive bay (top right). Totally isolated from the mainboard and cooled with two fans, also the holders are pretty sweet with a locking latch set up.

Liquid cooling setup. It weighs a ton!

Here are the PSU internals. The plan is to strip these out and replace then with an ATX supply's internals. I will save the inlet port and front fans for cooling.


Also, I've ordered some things for the modding experience.
Standoffs from McMaster-Carr. The plan is to glue these down which is why I got the ones with the most surface area.
16 pin header connector(for front panel)
10 pin header connector (for USB and front audio)
Header crimp terminators
Vertical mount USB receptacles
I also ordered some sleeving stuff from wirecare.com:
Flexo Clean Cut-1/8-black-100ft
Shrinkflex Polyolefin Heatshrink Tubing - 3/1 - 1/4" - White

Only some were cooled this way. As far as I know, just the ones after 2005. From what I have learned it wasn't water but actual coolant (like green car stuff). Aparantly they had a nack for leaking and making a mess of the computer.

lol But I can tell this G5s (PowerPC 970) CPUs ran hot as hell! I looked at some of the systems that had air cooling and the heat sinks were huge!

Yeah, cooling was a big part of the design for these. That is what I find pretty impressive with apple. I had always been of the apple is overpriced mindset but the effort and design that went into the cooling (with baffles, separated zones, custom PSU location and HDD fans) is pretty impressive. I still would never pay for an apple, especially since I hate OSX, but it gives me a bit of appreciation for the price.

I figured I would update this with a bit more frequency but I've been really busy lately with school, work and this project so I've nearly completed it and am just now offering an update.
I got the case welded by a local welder. It looks pretty darn good. The tack is visible but it isn't nearly as bad looking as it did look.
I've gotten the computer pretty set up and am currently posting from it right now. I still need to do work on the rear panel and I may get to that this weekend.
What works:
Rear audio.
Front button, LED, audio and USB.
Mobo standoffs(thanks JB weld!)
Optical drive with super trick door.
Optical and HDD stock power dongle.
HDD and rear stock fans.
Antec PSU in stock housing.
What needs work:
Rear panel USB and Ethernet. Thinking about getting a NIC for the ethernet and will be using some panel mount USB parts for the USB ports. I just like my internets too much to trust them to my solder jobs.
No speed control for stock PSU fans (very loud).
Mount 2x120mm front fans.
Overclocking!!! Once I get the front fans I'll try and take this chip past 4.0.

Pics:
Setup for testing stock fan pinouts.


Test fit with a mobo from my old comp.


Test fit for PSU in stock housing.


Start of my sleeving. Very happy with the result.


Six Cores!


Without PSU


Complete!


Rear panel. I really hate the look of the cable entering like so I will either make a short jumper or get a NIC.


Take that Steve!

Nice job Seahuston. I own a G5 dual with LCS and accidentally broke off a nipple from the waterblocks while cleaning it. Any help with old G5 waterblocks will definitely be appreciated. Let me know.

Thanks!
