Back in college days, I made my dell laptop a hackintosh, at that time ati was not supported by osx, so it was very troublesome to install - patching dsdt, kexts and all. It broke when I updated to Lion and I stopped and installed Arch Linux. I used to check http://www.insanelymac.com forum, http://wiki.osx86project.org, and, http://www.tonymacx86.com a lot. There you will find most of the resources you need.

You might find these links useful in finding a compatible pc if you don't want to do diy:
