For one, the mods frown upon discussions like this on here because it is not legal to install OS X on non-Apple hardware and talk of such things and how to perform it could implicate the forum and its members. Even the OSx86 sites make it very clear that it is illegal to do this and you're doing it at your own risk.
There are G4 Power Macs, eMacs, and some other Leopard compatible Macs that you can find for pennies now. They won't be as lightning fast as the Intel Macs, but they will allow you to run Mac OS X (even Leopard) and give you the Macintosh experience that you're looking for. If you don't feel like going through eBay, you can check out a list of vendors on the Low End Mac site for some great deals.
