Where could I buy the basic components (case, PSU, Mobo) all preassembled so that I can just drop in all the stuff from my previous computer (vid card, sound card, RAM) and play? I really don't want to have to build a whole system from scratch, nor do I want to pay the money to buy a completely new system. I'm looking for the middle-of-the-line path on this. Is there a word that describes such a system that could help me in my search? Thanks in advance.
