Well, I can report that someone wanting to mount a 5.25" drive in a IIcx
or IIci should do so very cautiously.

The IIcx/ci power supply is not very robust, certainly not on the order
of the venerable II and IIx.  I've discovered to my chagrin that most
video cards (or other Nubus devices) and power-hungry drives do not
co-exist peacefully.

MicroNet has fabricated a mounting bracket for use with their CDC
5.25" half-height drives in the IIcx and IIci.  The drive doesn't
interfere with any of the internal hardware or Nubus space.

Woe betide, though, if you want to run your Radius or E-Machines
video card (or, I imagine, many if not most other Nubus cards)
at the same time.  Given that the power supply is so wimpy,
you might be better off mounting the drive in a room of its own,
with its own power supply.

(Strangely, I can get the IIci to work with the internal 5.25"
drive and Radius card, but only when an external hard disk is
attached and powered up; without that, I get the sweet arpeggio
which denotes a hardware fault.  Removing all Nubus cards works
too, but you can't do too much without a monitor :-(.)
