I was aware of the first one, which is where I got the idea in the first
place.  12 drives is more than I'd need and that is a very expensive
case though.

I wasn't aware of the second unit.  That looks perfect, except it is
more than I can justify spending to make it a rack instead of a tower
(and 4 bay tower kits that use infiband aren't that expensive, plus you
can retro fit a non-hotswap SCSI tower cheaply).

If they were to do that, I bet they would charge about 3 arms and 2 legs.
