Finding my way through the Pile

My desk... Wait, let me back up.

When I use my computer at home, I don't use a traditional desk. My work surface is a solid core door laying on top of two deep file cabinets. I've used this system since Dan Brian introduced me to it while we were working at Clockwork Internet in the mid 1990's. Since then, the functionality of the setup has been hard to match, let alone beat (not for lack of trying). This will sound horrible, but the only way I can see getting more versatillity, space, and functionality would be to get 1) a Steelcase office setup, or 1) a custom build desk.

Now, it is true that I have a huge pile of stuff in my "office" at home, and lots of things find their way to the expansive horizontal surface that is my "desk." Perhaps with a more modest space (something smaller than 2400 square inches) would permit me to use just the things I need while keeping the other materials at bay, but I've not yet found the solution that is attractive and in my proce range. I'll have to keep looking... and quickly, as the piles seem to be looming, moving in, trying to take over my jasakfnasufasasdfalksfasleuraieuracn lseruluil zsifhn.
