Through the dedication and perseverance of the group of people known as the OSX86Project we have come to know a group of consumer hardware components that are compatible with certain closed-hardware operating systems. What Psystar offers is a customizable machine with hardware components that are fully compatible with the OSX86Project so that the end-user only has to buy their computing devices once and not have the endless headache of searching for compatible hardware and trying to return hardware which doesn't quite work. Psystar takes the time to fully test these machines to ensure functionality across the board.

The idea of the Open Computers is not to pirate the Apple operating system but to allow the Apple operating system to be run on hardware of the user's choosing. The premise of running OS X on an Open Computer hinges around the emulation of the EFI BIOS that Apple computers use. EFI was developed by Intel for heavy server platforms as an improvement over the traditional BIOS that is now approximately 365 million years old. Apple, so far, has been the only consumer hardware producer(reseller) to pick this up as the standard BIOS for their machines (totally ignoring the horror that is the Gateway 610 Media Center). This is the brunt of incompatibility between Intel Macs and Intel PCs. EFI replaced Apple's OpenBIOS (we like Open things) and although everyone is ready to get on the EFI bandwagon it seems that most (i.e. Windows Vista) operating systems will not be having native EFI support for some time. 

A great thing about Open Computers is that you can run Mac Book Pro or Mac Pro graphics cards at less than a Mac Mini price. This is all thanks to NVInject and the drivers put out by the community. NVInject just allows the operating system to recognize different types of GeForce video cards not endorsed by Apple and thusly not available.
