I have had one of those since I ditched the rack gear, and midi control pedal board(around 2006-7)for live use, and went all pedals. It held all my pedals, cabling, power supply and cables for that, and set lists etc. The lid can be used as a tray/pedal board. The hinges detach easily. Once I got things laid out, it was a good and easy setup rig...mine was kinda sloppy looking, but functional.
I moved to a Pedaltrain setup when the ten year old hinges started to fail, and I wanted to hide the power supply in exchange for more pedal real estate.
Thanks for that link...

Good point about hiding the power supply though!!!
