Short on Space

My office isn't quite working out as planned and it's bumming me out. There just isn't enough room and I'm about ready to tear down a wall! WE still have to keep clothes in it so there isn't nearly as much room as I'd like to have. One of my friends suggested mounting something onto the wall kind of like a rackmount thing for my computer to free up space. I think that's a great idea but I can't even figure out where that would go since I can barely turn around. I keep saying "for now..." but that's not really cutting it anymore...I need room!
