I have the perfect case for this out in the garage. Picked it up at a garage sale for cheap. It had an old VHS video camera in it. It's about the size of a medium sized Samsonite suitcase. I can't get it down to measure it as I'm not supposed to lift stuff yet.
Here's a picture of it sitting on the shelf though.
I'd look for one of these if I were doing a traveling office setup.
