[Beowulf] longevity of 1U servers?

I'm not overly fond of soprano choral works either, but they're not
_inherent_ to 1u-ism.  I have some 1u's with centrifugal fans that are in
their, uh, probably 7th year of service.  jeez.

arguably, those chassis couldn't have cooled dual-125W-socket boards,
but modern 50-75W cpus seem to be pretty popular...
