[Beowulf] Quiet *and* powerful

[Daniel Pfenniger]

Hi,

Its not a 1U, its a low-noise Linux P4 box, but really *low* noise: the 
transtec 1200
We bought these for offices precisely because these boxes are designed 
for low noise.

In practice in the office the box can barely be noticed,  I can imagine 
a dozen or more
of these boxes would not disturb a normal conversation.
