How about an array of orbiting servers?

Except that in space you only have heat loss due to radiation rather than conduction, which is quite a bit more efficient.
Add to that the cost of upgrading obsolete servers, and I don't (forgive the pun) see this taking off anytime soon.

Its been a while since my thermodynamics class in college, does the radiation given off depend upon the difference in temps? I mean, at some point a greater temperature differential would offset the loss of conduction, right?

My intuition would expect that an object at 60 C in a room with air at 59 C would cool slower than an object at 60 C in the vacuum of space.

Your intuition would be right for conductive cooling such as air/water cooling, but the amount of heat that is radiated only depends on the temparature of the object, the environment doesn't influence this in any way.
