What to do with a spare Mac case?

A local Mac dealer is requesting suggestions on what to do with
some extra G4 Mac cases they've got laying around after ripping
out all of the usabe parts. They've already got a gutted iMac
as the centerpiece of an iron sculpture on their lawn and someone
suggested using the case as a BBQ grill (after removing all of
the plastics.) Winners of the "contest" get one of the cases
stuffed with swag (mouse pads, etc.)

If you want to offer'em some suggestions, here's the link:
