Hardware

going about this in reverse. You fail to mention if your PC will even run OSX. Have you done due diligence in checking? Not many will. And those that do most often experience issues which surface later down the road. If you feel fairly certain that your system will run OSX and are fairly confident in your ability to install it, my advice would be to start with OSX and then install XP with Apples Boot Camp. However, I have serious reservations regarding your current skills in completing this project. Not saying this to be mean.

I actually applaud your desire to familiarize yourself with the Apple OS. I did the same myself. That said, while people claim how easy it is to use OSX, setting it up on custom partitions is not so easy. Not to mention your hardware issues.

Good luck though.
