So I just succeeded in getting the desktop I built to run Mac OS X Lion. With much help from tonymacx86.org (mucho thanks to the people behind it) I was able to get my custom built $600 desktop to run Lion just like a $2400 Mac Pro. It is a frustrating process and you will need some patience. But I shall post the specs of my desktop and the steps I took to get it to work, to make your life easier. Please make sure to purchase the software needed for this. I do not recommend using pirated software, especially when Apple provides it for a very reasonable price. Stay on the look out for the full details.
Hack a Mack!
