Building a Mac-OS-X-compatible PC

FlyingNosehair

I've learned that what ties Mac OS X to Macintoshes is that Macs use the latest boot system, EFI, from Intel whereas other PCs still use BIOS. However, you can get a motherboard with EFI from Intel. The question then is if I got such a board from Intel and then got these following parts that I took from the hardware specs for an iMac:

4MB shared L2 cache

1GB memory (2x512MB SO-DIMM)

160GB Serial ATA hard drive

8x double-layer SuperDrive (DVD+R DL, DVDRW, CD-RW)

ATI Radeon X1600 graphics with 128MB GDDR3 memory

would there be anything stopping me from running Mac OS X on such a computer?
