Thanks, guys! I will post some pics when it's all finished, but it's going to be pretty basic. I'll also post some pics of my old setup as soon as I find my old hard drive.

I've procured aquarium sealant, will clean the tank with diluted vinegar tomorrow, and seal the bulkhead on Saturday!
We're at an impasse with how to raise the tank off the ground. My father (who owns the house and is concerned about the weight issue) went from "I'll help you build a nice platform out of 2x4s and plywood" to "we're just going to stack 2x4s on top of each other; nails, etc are unnecessary because the weight of the tank will keep it from falling over. We're not topping it with plywood either." I think that's a really bad idea, and he's really stubborn, so that part of the project has stalled.
