I am no expert with macs, whatsoever, but my experience with PC repair and building has given me a little common sense when it comes to things like this. A modern mac is no more than a PC in disguise. they no longer use an alternate cpu as they did in the old days. They use all the same parts, same cpu's same video cards etc. So all you would need I imagine at worse case is the snow leopard O/S and the knowledge to set up a dual boot system. Then you can have a mac and a PC. I cannot see any reason that apple would not allow this as they sell their O/S's on the net.
As long as your PC is fairly modern, dual or quad core and intel based (not sure if the mac O/S will work on an AMD, but as both companies work together to keep compatibility problems down,they probably will.), the mac O/S should work. Anyway just a thought, as a lot of people tend to assume a mac is totally different to a PC. They would be correct but only with the old macs. IBM pretty much forced them to change when they dropped the Power PC chip.
