You may also consider visiting the Hackintosh website. Here, they explain how to run os x perfectly on windows hardware. Now that Apple is Intel, a few lines of code, and you can have a Mac Pro at a Dell price. I have been running this exact machine for over a year, without hiccup. If you are serious about a Mac but don't have the dosh, you can build a cheapie, and have your Mac as well!!
