  No, according to Quantum universal configuration guide I got at
http://service.quantum.com, it's a mini 40pin(J2, SCSI connector) and
8pin(J1, power supply one, only required 5V) connector which are
fabricated from one mini 50pin stuff, 3M series-150 50pin connector(pin
9, 10 and 27 are removed, so it's actually 47pin).

  Well,...  Not sure, though 1,3,5,7 pins are GND and 2,4,6,8 pins are
5V or something?

  PS/  A guy on netnews told me that 2.5"<->3.5" SCSI adaptor, which
comes with adaptor board and drive bracket for 2.5" drive to fit in 3.5"
drive bay, is avilable.
  Thanks for your help, guys!
