Eric,  Sound to me like he got a bare drive and no 54-xxxxx boards
and PS to make a complete rx01.  Iv'e found the base mechanics are
common as people part out rx01/02s for the boards or PS.

Brad, 
If you listening the real RX01 is heavy, two drives
in a rack width cab nearly 11" high, contining a
powersupply and two long cards that supply drive 
interface (for both drives) and processor (nearly a 
complete FDC in itself).
