Okay, so I got it together. Now, I went to start it up, and it ran fine for a few seconds, and then shut itself off. The specs are here
. I've gotta go to work now, but I'll be back in 5 hours to answer any questions.
: I've fixed the problem. I hadn't installed the heatsink/fan properly. The pins weren't all the way in, so the CPU wasn't making a tight connection, which cause the power down. It's running fine now (has been for about half an hour), and I'm half way through formatting my 160GB HD. Now it's time to relax. Thanks to everyone who tried to help, and I hope no one else makes this big of a newbie mistake.
