Installing OS X on a Hackintosh (PC) has become simpler
It used to be that installing OS X on a "Hackintosh" (an Intel based PC running OS X) was an involved process that took hours and hours of hacking to get to work properly, sometimes with mixed results.
According to Lifehacker, you can now install Leopard on a cheap PC almost as easy as installing in an Apple device, sans the wicked command line hacking. Also, you can reportedly update your Leopard install without the fear of all your hard work falling down. It must be stated however, that installing OS X on a non-Apple product may be illegal, even if you have a legitimate installation disc. Proceed at your own risk.
The technique does not require a BIOS reflash, but just tweaking the BIOS settings to be friendly to the OS X install program. Next you download the DVD image and burn it to a DVD for use installing Leopard. We'd recommend actually buying Leopard if you're going to be using it for any amount of time. The final step involves booting the new DVD and running through the install process using the settings for your specific motherboard.
