:idea:
Here's one I thought of some time back. A 1.9 cu ft mini freezer @ 20" square. It has a thermostat that can run the unit to -20 C. It's under 200 bucks.
My idea was to trash the door and replace it with a triple pane, argon filled thermopane unit with the "heat mirror" film inside, (blocks most infrared transmission), set in a frame and installed with a silicone gasket held on with thumbscrews.
Mobo set inside on plastic standoffs with ground wires at top of standoffs running to silicone sealed connectors at side or top of unit along with all other needed wires to PC case, with all other components (psu, drives, etc), mounted on side or top.
If heat load is to great for freezer then............................
Cpu and Gpu to have heatpipe coolers that have enough space between base and fins to allow fins to be sealed in insulated, sealed "through" duct with 120mm fans.
Fill Port and purge valve to fill sealed freezer with nitrogen to eliminate all moisture.
Pc should work great even with freezer unpluged. Even better turned on and set to -20 C cooling entire mobo, ram etc.
How about one of you guys with more time and money than me build it and let me know how it works

Oh ! by the way HELLO. Been a lurker here for YEARS.
