New Hobby (God help me)

Well, on Friday I purchased a new computer case with the intent of building it into a fully operational computer using nothing but a few tools and my phalanges. This son-of-a-gun has 11 drive bays, dual chamber structure, 7 expansion slots, three layer side-panels for noise dampening, 5 fans...I could go on forever. What I'm trying to say is that I'm in way over my head. With my rotten luck I will manage to cause a catastrophic power surge and black-out the entire western United States (lol). Wish me luck. I'm going to purchase the CPU and the motherboard sometime in the next couple of weeks. I'm finalizing my research on what brains I want running this over sized hunk of junk before making the expensive selection.
