WHEW!! It was only the pump that was bad. Water leaked out of a fitting that worked loose due to torque on the tube, dripped into the pump housing, and shorted out the pump. Replacing the pump fixed the computer, no damage to cpu, gpu, motherboard, or drives, thank goodness.
I did realize just how dusty the insides are though, so I'll have to disassemble and clean everything. I also want to add a water block to cool the RAM (and make it look awesome). And I really need to work on the lighting and cable routing some more.
Unfortunately, the 20" white cold cathode tube I bought had connector problems. The connector fell off. Whoever crimped on the pins didn't do it right, I think. So now I need to contact the company that sold it to me and have them either fix it or send me some new pins which I can crimp on myself.
I have a great place in the case to mount the 20" light bar too... just need to have one that I can power up is all. I put a UV cold cathode in until I can get the white one working... that gives a fun glow, but not quite the look I want, so I'm going to change to clear tubing, blue fluid, and white lighting, I think.
