Alright, my first post Anyway, I've had it with my PCs. Every time I get windows, it works for about a year before having some horrible error that destroys it, (4 times, 6 if you include 2 laptops). Well, my HP has lasted about a year and a half, but I'm also just sick of vista that came with it, so I'm switching to Mac. I'm getting the Mac Pro, and I was wondering if I can rip out my PC parts and put them in the Pro (3 gigs of ram, a 8800 geForce card, the sound card, and if I could, the harddrive). Is that possible to do from PC to Mac?
