For starters, here's my (admittedly messy) desk at home.
To be honest, it's not even a very good picture. I have a nice, high-back desk chair, a widescreen LCD at hte center of my desk, a full keyboard, and my Mac to the right, on top of my unused printer. Out of frame to the left is my tower desktop, for when I need Windows or blow off some steam (and take out some Team Fortress 2 punks). The desk itself is rather small, and the room is in pretty good shape beyond the desk area.
I'm comfortable with this style and layout, although it is a little cramped, but it provides a good basis for a dorm room layout because it is compact and because I can't make any permanent changes without angering my parents during my summers at home.
- Keeping the tower to the left of the desk keeps it both out of the way and easily accessible. As a bonus, its flat top is a nice place to keep blank CDs, headphones, and the power adapter for the Mac. Here's a photo:Tower, with some stuff on top of it.
- The laptop can't stay where it is. I don't use the printer over the summer, but for school I'll be generating a decent amount of paper with all the fun papers and source code I'll be writing.
- The plastic drawer and cabinet come through once again. I don't know where I'd be without those two bits of storage. They're dirt cheap, reasonably durable, and easy to find. Staples has a good collection of plastic storage boxes here, in their online store.
So there's my starting point. Next I'll start to finalize a plan, followed by a suggested parts list.
