I can possibly round up enough 18G drives to populate the
box.  But, it would be quite annoying to find that it
was an exercise in futility (since I would have to backup
each drive before risking the drives' contents in the array).

I'll have to dig up some FO cable and set up a host with
the proper SBUS card...
