I succeeded in building my own mid range M[h]ac Pro.
Here is the specification list that is confirmed to work.
The motherboard plays the most vital part to successfully run OS X Snow Leopard on a PC.
The guide from lifehacker used a different motherboard but it works on this motherboard nonetheless.
*Another guide specifically for this exact motherboard variant.
The BIOS setup
This is very important. Again, I followed the setup from lifehacker.
Slight Difficulty during the Installation
In the video by lifehacker, the part which you have to choose to boot Snow Leopard from hard disk:
My VGA display just turned black with "Input Not Supported" text shown.
As the video suggested to use the arrow on the keyboard to boot from hard disk, I just tapped the right arrow three times and pressed Enter, ignoring the "Input Not Supported" text.
Surprisingly it worked.
Sound
Everything works out of the box, Ethernet, Graphics, USB...etc. except sound.
I got my sound working using the kext (equivalent to driver) from this website.
To install the kext use this software.
M[h]ac Pro updated to 10.6.1 via Apple Software Update website.
