...or it just means the single cases are even more unreasonable.

What I mean is $114 is a lot to pay for what looks to be $40 worth of

Of course, if no one sells them...

I have a 4-bay narrow SCSI case now that has my tape robot and one SCSI
drive.  It works fine, it is just a bit bulky for what it holds.

That's one thing I liked about the Sun 711 we had at work 2 years ago.
It packed a lot of drives into a relatively compact space if you had the
one with the dense backplane.

I have ideas for case designs that could stay cool and hold a lot of
drives, but I don't know anything about metal working.

One ideas is to enclose metal drive bays in some other material I can
work with.

My current case might be able to fit more drives in if I play a bit, but
then I'll probably have cooling troubles.  I'm still thinking about that
and how it might be solved.

Well for me, it was a way of testing and switching operating systems.

Swapping a drive tray takes 30 seconds.  Opening up my case and
switching drives takes a great deal longer, and involves a lot of
