Another Power Mac G5 Mod :D

10 posts in this topic

Recommended Posts

hey guys,


so here is my G5 Casemod. About a year i had the idea to install osx on my PC. 4 weeks ago i finally bought my new PC and assembled it together. OSX 10.8.2 is running smooth on my system.


My System:


Apple OS X Mountain Lion 1.8.2




Gigabyte Ga H77M D3H (mATX cause of casemodding a G5)



Intel Core i5 3450



Gainward GTX 560 (nonti) (natively supported !! no extra kexts !)



Kingston Value Ram 16GB 1333MHz (4x4 GB)



cheap Samsung CD/DVD burner



Cougar 450W


Already Owned:



Seagate Barracuda 250 GB



Acer 22" TFT LCD


Mouse + Keyboard:

Logitech Mouse + Apple Keyboard


at the same time i bought an old power mac G5 case on ebay. it was broken (cpu). i read a lot here about casemodding a G5 and where the difficulties are. I decided to go the hard way and let this beautiful case his clean look icon_e_biggrin.gif that meant i had do solder a lot with ab bit of cutting and gluing. For the additional cables for USB, Audio and Ethernet i used my old case. it had plenty of it icon_thumbup.gif


this is what i am modding



and this is the case after disassembling icon_e_biggrin.gif some parts were hard to remove ! i like how apple thought about the airflow in this case. maybe i can reuse some of the metalplates to get a better airflow.




"unboxing" the PSU icon_e_biggrin.gif i will reuse the old plug and wire it to my PC PSU




this is where you have to solder the audio out cables




and this is the soldering position for the 2 USB ports




the soldering station i used



prepaired cables right before i soldered them.



audio and Usb soldering points (not marked yet)



thats where the problems startet. audio is bit too quiet... i guess its the soldering. i didnt do it right. the USB ports dont work at all. but a big goal was that ethernet worked 100%. i have 32.000er DSL and the tested speed through the soldered Ethernet was 29.000er and upload 1000. good enough :D

i also costumized the PSU. i was fitting it into the Mac's PSU case. I cut the PSU plug and reused it for my PC PSU. works just fine !

aaand then testing the soldered PSU with my old Core 2 Duo and my 9600 GT. i also rewired the apple original PSU fans (carefull: they are loud) just solder the black cable to the red wire of the connecter and black to red connector cable. they are cooling the PSU quiet good icon_thumbup.gif



at least i soldered the front I/O cables after a scetch i found here on tonymac. just cant find it right now. problem was that the cablenumbers on the sketch were different to mine. but i just had to change 2 pins and the power button and the LED worked.


this is the "final" prototype of my running system this evening. i tested all components and they work. now i have to build in HDD cage, dvd drive and my (hopefully) better soldered rear panel I/O.



the next day. i bought glue to glue the original mobo mountings to the back of the case. this costs 8,50€ and is epoxy-2-components glue which is mixing automaticly.



This is a close look on how i glued the pins onto the case



after waiting for about 90min (30min blow drying cause the glue is stronger when its drying at about 40-70°C) i glued the rear I/O plate in its right position

this is how the rear I/O looks. nice and clean without any cutting icon_thumbup.gifheadbang.gif

it depends on what ethernet jack you have. then type "ethernet pinout a" or "ethernet pinout b" into google searchbar and click on images :D

How did you manage to get that UTP socket to work?

Did you only solder the 8 data wires or the 2 extra wires too? (it's a 10pin socket).


I didn't get it to work because it has an internal isolator which prevented the thing to work if you solder directly to the pins;

normal way with a connector does work though, very weird.
