I know what you're talking about now!
During my school's Fall Break, I took a trip to Denver Co. and visited the Apple store...
But before that, I visited DaVinci Technologies. I went there to gain a bit more knowlage about building my own PC... Needless to say I learned a LOT more than I thought I would! I've gotten a shopping list put together, and I expect to start building by next year at the latest.
But for now, at least, I will know what all of you are talking about when you mention Motherboards, or power supplies. etc....
