This is the forepeak of my sailboat, which serves as my bedroom, study, and exercise studio (the ping-pong table and flatbed scanner are stowed). That case is fitted out with extra fans in the sides to keep it cool. Note the lashings to keep it in place - the VCR and printer are velcro'd in.
I cleaned it up some. I thought it was pretty messy until I saw some of the others here, but I feel much better now.
Good luck, everyone!
