Good idea, but I think a plastic box would be better. A GOOD plastic box, but plastic nonetheless. Metal is just...ungainly. Heavy, unyielding, scratching everything.
A powdercoated black box has its charm, to be sure, but folks have to live with these things.
I still have my original Traveller...uh..."box" though, to be fair, it's not very box like anymore.
In fact, it's almost, but not quite, completely unlike a box.
