My desk is actually pretty tiny. Sometimes I can hardly fit my monitor on it, it seems!
Hey, my little brother's computer is about that old, iirc, and it's still alive. I don't know how, but it is. If that works, I'm sure yours does too. Have you upgraded it any since you've gotten it?
Every once in awhile I sift positions, but otherwise it works out. And since my computer's so close to my keyboard having it wired is no big issue. I don't want to spend the money on something I don't desperately need.
