For the record though KNC decision to use a case which requires the PSU to be outside is equally stupid.
I think that might have more to do with regulations in the EU about selling stuff that plugs into a wall socket than it is about the proper management of heat inside the case.
Nobody said include a power supply. We are simply talking the exact same sheet metal case but wider. The silliest part is the stated design was for rackmounting however the case isn't standard rackmount width (19"). So it is smaller than what is needed for room to house a PSU and due to its size it can't be rackmounted without a shelf. If it was a 4U 19" rackmount case there would be more than enough room for a PSU and it would rackmount directly.
Personally I see the semi-useless case as a waste of money. If you are going to use a worthless case design then just drop the case. Simply ship the hashing boards and control board and let the user supply the case.
