TN - As others have said, while this can be done, if you are truly interested in this platform, buy a Macbook or iMac. A Mac Mini would be the best bet and cheapest. You can find one of those on Ebay for cheap for a model or two behind.
That being said - It can be a fun journey/experiment to get to work right. VIN86 has one working perfectly and I have one on my PC I dual boot with Windows 7. I use them both.
