Thanks for your suggestions.
In the meantime I had found this case and PSU - what do folks think?
Antec Twelve Hundred Gaming Case -
http://wiki.dandascalescu.com/reviews/gadgets/computers/cases#Antec_Twelve_Hundred_Gaming_Case_.E2.98.85
+ 12 5.25" externally-accessible bays, in which you can
elastic-mount the hard drives
(http://www.silentpcreview.com/forums/viewtopic.php?t=8240)
+ under 28dBA SPL @ 1meter at 100% CPU fan
PSU: Nexus RX-8500,
http://www.silentpcreview.com/article970-page7.html
It has a relatively constant noise profile 28 dBA at 300W, 33 dBA
@ 700W
Not sure what wattage the system will use most of the time though?
If it's under 400W, then the Antec CP-850 doesn't exceed 14 dBA -
almost silent.
I think you'd be better off with a NORCO for a cheap storage server case.

I guess it all boils down to exactly where this machine is intended to
be placed, as to the tradeoffs between performance, cost, acoustics, and
heat.
IMHO, server devices belong in the basement, which is most likely to
provide the environment most conducive to the primary mission of a
server - performance. Basements are most likely to be free of the
acoustic and heat constraints that having a server in a living space
forces upon it. Who cares if it shrieks like a banshee and puts out
enough heat to melt ice if it's parked over by the dryer?
If you have to have the server in a living space, well, you're going to
pay in performance and cost. At best, you can dampen acoustic concerns
(no pun intended) by isolating the machine in a closet or other place
where insulation of some time reduces sound. However, you pay for that
in a severe heat increase. And tricks to reduce noise are going to come
at a significant performance penalty and monetary cost.
It's that simple. Personally, I've shifted to 2.5" drives for a lot of
reasons (performance and per-spindle reliability, mainly), and they do
cut down on noise and heat significantly. They're more costly $/GB than
3.5" drives, though, and you're going to have either buy a case that
natively supports 2.5" hot-swap carriers, or invest in drive cages.
I'm a fan of the Supermicro 2U cases for 2.5" drives. They come with
excellent power supplies, and are quiet enough to use in a closet, but
they're hardly cheap ($700+, depending on model).

In your case, I'd also consider a design which has EXTERNAL drive bays.
eSATA is the cheap way to connect them to a server, and this leaves you
with better case choices for the machine itself - smaller, cheaper, and
quieter.
