Or you could just take a dehumidifier and modify it to do this for your PC. They are much more efficient on their use of power than TEC's.

If powers not an issue you could do it quite easily though. Having the cold side of the pelts dehumidify the air... then have the cooling loop from the hot side run through a radiator that the cooled air goes through and heats back up. Essentially you are building a disconnected thermal "short" in a weird kinda way. Just pumping lots of power, into something and getting almost nothing out of it.

Also making an effective cooling surface that collects and drains water as desired is also something to work on.
