just a few things.

1. LN2 is a very temporary cooling solution. they designed all these setups to get to the speed, run the benchmarks, then dis-assemble the system.
2. It evaporates pretty quickly, so isn't good for anything but an afternoon of high overclocks and frozen roses... cummon, you all know that everyone would stick things in it just to see how fast they would freeze :P
3. You cannot 'resist' the freezing effects, it is condensation that you must really worry about, because that is water, and water is bad when in direct contact with electricity.
4. It is very expensive.

I could go on and on about why not to do it, but you will be the one that chooses to in the end.
