Virtualbox is a virtualization suite that works for Windows- installing Mac OS X on a virtual machine in Windows before doing it on your actual computer is great practice, and it gives you a chance to determine whether you'd actually prefer OS X over Windows. If you need help deciding whether to make that leap of faith, then you can try installing Mac OS X Snow Leopard on Virtualbox, instead.
We've already covered how to run a Mac OS X virtual machine with VMWare Fusion on your Hackintosh, but that tutorial won't do you much good if you haven't installed Mac OS X on your PC yet.
