I'd recommend trying the 360N, I've seen the single p4 substantially
outperform the dual (even with 2 jobs running).
Basically the memory bus is substantially better on the 360N, and it's
even quieter then the 650N. Of course this depends on the worldload.
I've never heard a quiet 1 or 2U. Even the apple xserv's are pretty
If building yourself I recommend a case with rubber grommets, and
slow RPM 120mm fans similarly mounted. The Antec Sonnata is an example.
Other possibilities include placing the servers elsewhere and using
a small quiet machine with an LCD/keyboard/mouse.
