Kash, I have worked with cooled electronic systems for 15 years. They are not fun because the reliability is poorer.

Moisture condensation is a primary problem. The moisture inevitably leads to corrosion of most electronic components. The only way to limit this problem is to encase the system is a hermetic case, and have vacuum inside the case. Unfortunately the vacuum suffers from minor leaks, and unless the system is pumped down annually you are asking for trouble.

Temperature cycling is another headache. Cooling the system causes mechanical stress [ due to different coefficient of expansion of materials inside an electronic system, causing wires and cables to crack and snap].

Most of system failures show up in the first week of January. Despite explicit warnings, people tend to shut down systems during Christmas,[ the environtmentalists insist on conserving energy], causing the electronics to warm up, and the condensed moisture to melt, leading to corrosion. In January the system is powered back, and the failures due to corrosion and the temperature cycling show up.

In summary cooled systems are much less reliable. Kyrotech cooling is OK for a supercomputer installation, but not for the average desktop.
