My shop is usually dirty...this is after a cleanup. I figured I better take a picture before I mucked it up again.[

I've had the computer in there for three or four years and it's never failed. It is nicely convenient for CAD, email, forums, plus, as an IT director, I am always plugged in to work. Every now and then, I clean it out. (I was a computer tech for many years so I keep it pretty well maintained)
