Since power & cooling is almost always free for .edu's, yes, .edu cluster
design and others' will be extremely different.

Not to mention that .edu's cant stand losing nodes in a throwaway 
design that accomodates tolerable rates of failure. (Anyone operating
a cluster in this mode? Im very curious as to how you surmounted the
psychological objections to it!)

When you say 'TCO' you REALLY have to define what you mean -- "total cost
of OWNERSHIP" or "total cost of OPERATION"? You can own a really nice
cluster for $x if you dont have to cut $x into slices to buy it
AND pay for running power and cooling for it for n years.

Anyone admit to being in the 'must pay for power and other operationals'
camp and want to explain how their designs differ? (especially those
that pay a premium for floor space - these edens start winning on two
fronts. Low heat = low space requirements.)

I suspect EDENs will be viable for people in the expensive power & floorspace
areas (Bay area, etc?)
