This isn't really possible. Apart from the problems of lack of space to put an opening bay (no room on the front or the back of the unit, and the sides are fairly structural) the drives are held in a shock-mounted bay inside the unit. Ok, it'd be possible if we had a *lot* of money to throw at the engineering of the unit (maybe a bay holding the shockmount and the drive?) but this is non-trivial.

The connector design for two IDE busses could be fun too, as it would have to dock without opening the unit.
