The solution to condensation seems fairly simple to me. Before you can use the system, you need to wait a few minutes for the CPU temp to drop. Why not also design a closed-loop "air conditioning" system for the case, which would dry the air inside the case and prevent moisture formation from occurring at all? If you're pulling the CPU down to -20F, then it seems reasonable that you could also have a small evaporator coil for removing moisture from the air inside the case. A closed-loop system would also have the advantage of keeping the system dust-free, since the same few cubic feet of air would be recirculated continuously inside the case. The system needs time to cool the CPU before turning it on. At the same time the CPU is cooling, the small internal A/C could be removing moisture from the inside of the case prior to startup.
