Be careful with that, the Mac fanbois will wipe the floor with their TOS. It's even ironic that every Mac user is in violation of the TOS. According to the Mac OS TOS it says that you can't install it on non-Mac hardware, but guess what is inside of a Mac? PC parts.
The OS X EULA says that you can install it on "Apple branded" hardware. Therefore your argument doesn't hold water here, since every mac is "Apple branded" even though it uses PC parts.
