Oh no, this has all been discussed before on the list before (many
times, actually -- look back at the archives with google to find some of
them) and MY favorite solution is to build a really large computer room
in, say, Antarctica and just put fans in the windows.

Liquid solutions (no pun intended:-) tend to be expensive, messy,
environmentally nasty (if you don't use water), risky (water and
electricity don't mix well) and, as you note, servicing the machines in
a full immersion rack can be, well, "involved".
