This doesn't pertain specifically to Mac Pros or Power Macs, but I couldn't find a better place for this. Is it possible to build a Mac from scratch, like a PC? I've looked everywhere and I can't seem to find what proprietary hardware, if any, Apple still uses. I use a macbook right now and I'm wondering if it's as simple as booting with the Leopard install disc. On a similar note, is it possible to use boot camp on a separate internal drive rather than partitioning an existing one formatting for OS X?
