Ok So I keep hearing people say Mac pros are way over priced, you can build one for way cheaper then just install osx. Well, I had a PC sitting around, and some spare change so I decided to build one. I didn't have much money so i bought parts equal to, but not as nice, as the parts used in the 2006 mac pro. (ebay ftw). So I put the computer together, pop in the OSX disk (kalyway 10.5.2) When I try to boot up I get an error, google it, turns out my dvd drive isn't supported. I put the installer on a usb drive and boot it up. I install leopard and restart. After booting up, I find 1) I don't have sound, both input or output, no ethernet, and my graphic card doesn't work with it. To make a long story short, for the time I spent working on this computer to get it to even boot and the money I spent on parts, I would rather just get a job at mcdonalds and buy a mac mini.
