Beyond water cooling. (Was Re: Peltier devices for cooling)

[Jeff Brown]

You have to purge the box with a nice, moisture free gas - like bottled
nitrogen maybe - to avoid frost.

S'nother problem. Mechanical deformations with temperature. CD and HD drives
go out of tolerance when the get very far from 70 deg F.
Even crystal oscilators (i.e.; CPU clock) detune somewhat.
 BTW, I used to work on a huge mainframe computer that was water cooled -
and all discreet transistors.
The IBM 360/95 designed by Seymor Cray!
