Before Mac Leopard, it was not easy to install Mac software on a PC. Mac operating system is not made to run on Intel processors. But now that Apple is releasing Intel-based Macs, you can install Windows on a Mac, and with a little bit of hard work and license-breaking, you can install OS X 10.5 on a PC with an Intel processor.
Don’t expect everything to work properly. Most will experience some missing drivers for graphics cards, audio, or even WiFi. But the installation process doesn’t look too complicated. All you have to do is, download an illegal disc image, patch it, install the operating system from a DVD and then install another patch.
The best bet is to buy an Apple computer.
