Building my first computer. Any advice/suggestions? Tommorrow, as part of my A+ Certification, we'll be assembling one in class. Tonight, however, I'm drawing up plans for the one I want to build for myself. Right now I have a Mac G3 and a Toshiba laptop. This will be a PC desktop I'm building. Would love some input from someone who has done this before, mainly on how to get the most bang for my buck. That's what Hugh Grant said, doh!
