"they" already do this for electronics.  Rittal for example make many
enclosure climate control products.  <URL:http://www.rittal.com>

I'm not sure it's cost-effective though -- you still have to get the
engergy from the room to the great outdoors somehow so unless you want
to run plumbing to air/water heat exchangers for every cabinet something
like the old mainframe days....

Again, "they" already do!  :-)  Rittal's climate control BUS system is
one example; APC's environmental monitoring card is another option if
you're using their UPS'.
