I'm moving into a dorm in about three weeks...
Over the past few years, I consolidated the huge setup (we're talking some 25 feet of table, several PCs and monitors, lots of equipment) I had at my peak of nerdiness into the current 4' wide table I have now. Right now, I have a microatx computer, a big LCD, keyboard and mouse, very small reciever (designed for a CD shelf system, it's a reciever with DVDP that's about 8" wide) and a pair of little Mission m70 bookshelves. Very compact. I'm replacing the desktop with a laptop and docking stand, so I won't have a permanent desktop PC any more. No need for one.
Then I talked to my roommate, and he's brining some ridiculously complex PC setup (I guess that's what I get for going to a tech school) that's obviously going to be really loud and huge. At which point, I decided, to put it elegantly, "**** it, I'm not going to make do with some wimpy little Onkyo just to save room, I'm bringing Jahn's Darth Opto and my BIC speakers"
So, I'm now trying to sell the Onkyo and the little speakers it came with to a friend of mine who is more concerned about space than I am. I figure that when I go, I'll bring the mission speakers and my little Kenwood receiver (which is small enough that I can leave it on my desk under my LCD), and the big BIC speakers, and the Opto. I'll try to fit the big setup in my room, but if I can't, I'll fit the small one in.
