Man that was a terrifying experience. Got pretty confusing hooking up the power supply and front panel stuff and I had to remove the motherboard about three times for dumb mistakes. Then when I first turned it on only the fans spun for a few seconds, except the cpu one. At this point I was wishing I got the dell after all. The wires around the cpu fan were right up against the blades preventing it from spinning so I fixed that and then all the fans spun for a couple secs. Turned out I needed another power supply plug to attach to the motherboard. I thought I had needed an adapter since it didn't look like it matched up exactly (and read conflicting stuff about it online with folks having the same problem saying it wasn't required)...but it did fit. And then, bam, everything worked. And I even got my old hard drive up and running (transferred the important stuff over but pretty cool that I can just use it as an extra one now). My previous comp was a barebones shuttle so the "building" was pretty much just plopping in the cpu, hard drive, and disc drive. Phew, me am happy. Can finally get back to work.
PS:
I got two 2GB. Was half the price for half the ram. Bought before you posted. Still have two more ports. Can upgrade to 12 and then maybe 16 down the line replacing what I have.
