Building my first comp...I have just about all the parts I need except for a CPU and video card. I figured that I may as well wait, in case prices drop in the week or two it took for the rest of my parts to arrive. Anyway, most guides suggest installing the CPU into the mobo first off, before the rest of my peripherals and drives. Can I skip that and install my RAM, sound card, etc. now? Or, is there some kind of technical issue behind what I install first and what I install last?
