I can't tell if it's real or not... even if it was though, I wouldn't use it. I use Macs, and wouldn't have any interest in poorly built PC's, even if they could run OS X (illegally).
It was bound to happen. There is PearPC and there was CherryOS (I'm not too sure if it still exists because its web site doesn't exist any longer) that made OS X run on Windows and that was to run the PPC version of OS X on an X86.
I am sure there will be many OS X emulators in the future since OS X is going to be compiled for X86 processors.
