As said, it is against the EULA to install OSX on non-apple hardware and it does require a modified OSX install to get it working on x86 systems. However, it possible and does work (and can be just as stable as an Apple machine, i have no issues).
OC forums isn't the best place for this, as i'm sure it's against forum rules, but if your serious about creating a hackintosh then Google is your friend (plenty of sites about).
