I have been working on a hackintoshed Dell for the last year or so. Initially, I tried to work with Windows 7. It really is not bad at all, but my brain seems to be hardwired to use a Unix command line (and Vim) at this point, so after a while, I had enough and sought refuge in Linux-land. It didn't last long though. After fiddling with the Nvidia drivers for a while to get a multi-monitor setup working, I decided that I could just as well invest that time in getting it hackintoshed. Amazingly, that worked flawlessly (nearly: network and sound didn't work. A USB-ethernet adapter and a USB sound card did the trick, though). Then came Lion and that broke my App Store on the hackintosh. So it's back to a genuine Mac for me.

It nearly worked, though. I wish you the best of luck.
