I've found the desk I'll be building next May when we move.
http://linustechtips.com/main/topic/63380-the-easy-option-for-a-computer-desk/It's cheap, easy to do, and I don't have to go buy any wood working tools.
The space that my girlfriend have to work with right now isn't large enough for this monstrosity. So, I went ahead and ordered two of the LINNMON 47 1/4 x 23 5/8 table tops with 8 legs. This will give us enough space for my desktop, grad school stuff, and hobbies and her nursing work space. It should be here around December 27th. If I like the IKEA parts I ordered already, I'll go ahead and order two of the 59" x 29 1/2" LINNMON table tops, the drawer cabinet, and some sort of file cabinet to supplement the space with more work area.
It's just a simple setup right now, but I'll take a few photos of the room when I get it setup and post it so you guys can give me opinions on what I can do next. I'm ADHD, but I don't take the medication anymore. This constant need to change things up is a side effect of the ADHD, but I kind of like it so I don't see the need to fix it.
