i) Absolutely no discussion of where or how to obtain copies of licensed software. We will always assume that you are working with a retail copy and you will not tell us otherwise. For the record ... everyone absolutely should go buy a copy of OSX if they are using it. Apple deserves to get paid and they charge a fair price for an OS + productivity software (iWork and iLife are both available bundled with OSX for less than $200).
ii) Installing OSX on non-Apple hardware is a grey-area as far as their EULA is concerned. We discuss installation of OSX on a 'Hackintosh' in generic / theoretical terms.
iii) Do it.
