Though it's not helpful, I have to recommend any case by Superpower. They're huge, heavy, and impossible to find these days, but they are built solid, won't cut your fingers when inside them, and will make sure the floor under them isn't going anywhere for a while.

Of course, this requires quiet fans, which I can't find to save my life. There MUST be some kind of coolophile high end cpu/case/psu fan seller online, but I can't find them. I must get some high quality quiet fans!
