RE: quiet dual dual-core opteron

I have put a few together for engineers where I work.  The low power single
core units were expensive, but made a huge difference.  I used a Quiet PC
power supply and case fan, a large Chenbro tower case, and two of the Zalman
7000 (?) CPU sinks.  Almost silent except for, yes, the SCSI drive noise.  I
will probably be doing a few dual core units in the next month and I will be
using the new Zalman 9000-something cooler and essentially the same setup.
I can list the specific part numbers later today if anyone is curious, but
the low noise case fan, power supply, and CPU sinks were key, and the low
power (HE, I think) CPUs made all of that possible by not forcing me to move
a ton of air.

I've got a largeish EATX thermaltake xaser3 case (next size up from standard

midi towers), Tagan PSU, Zalman CPU coolers and a Tyan S2885 motherboard 
(though the S2895 is probably a better bet for new systems).

The CPU fans are temperature controlled by the motherboard (and rarely get 
above 50% speed) and the case fans are on a fixed 40% speed controller.

It's not totally silent, but it is quiet even under heavy load. Like a low 
purr rather than the roar generated by most PCs. The noisiest bit is the 
harddrives clicking when accesses.
