I'm not sure I follow... is there some cost for air that I don't know about?
Sounds like you have quite a plan Emperor Que. I do feel that watercooling the CPU and GPU is definitely the way to go, especially if you're using pelts. Just this simple thing will remove the vast majority of the heat created inside your cylinder and dump it outside. It would make cooling the inside of the chamber that much easier.
I was wondering if you could build an air chiller for the cylinder using a couple of heatsinks and a pelt (I bet it would be a fairly low power pelt at that). Have one heatsink in the chamber that's cooled by the pelt, and circulate air through it. The other sink cools the hot side of the pelt. I am envisioning some sort of setup where the two HSFs are on opposite sides of the cylinder walls, so you'd have to deal with another hole, but it may be worth thinking about (then again, maybe it's just a dumb idea). Alternatively, if you used a waterblock to cool the warm side it could simply be added into your coolant loop, and be contained completely within the loop.
[EDIT] One other thing to consider, unless I've missed it: how are you going to prevent heat loss from entering the cylinder from the outside environment? Are you going to insulate it? If you don't I'd be surprised if you reach an internal temperature of say 5°C.
