Supermicro's high density file server is an even clumsier design where 
half the hotswap bays are on the back side of the machine.

You don't have to take down an entire box.  The design is just a dirty 
homebrew version of Sun's Thumper boxes.  The drives are still on a 
backplane and hotswappable.  You merely have to slide the machine out on 
its (very stout) rails and open the lid to access the hotswap bays.
