Regarding the case:  What I would like to see (with the 1.2 th/s rig) is a shell that encases the system for shipping, but that can be easily removed when the unit is placed in a safe place for operating.  Once removed the chips are open to the air and a fan can be used to evacuate the warm air from around the rig.  This makes for a happy operating rig.  Forget the fancy shell, as long as it hashes, that's all that matters.
