I'm back with a fully working desktop. w00t!
God, I love my backup server.
It's like I haven't missed a beat. All my settings and everything are back.
I should note, that the only thing I was able to recover off the machine was my unreal tournament maps and mods. Everything else was toast, and the machine was fully reinstalled from the ground up. 4 hours later, and I can't tell anything bad happened.
