You gotta remember, colder is not better. IIRC, the optimal ambient temp/humidity even in a data center is 68F/45%. Run those AC's at 68F, and you're good.
You may want to use some of these Peltier units :

I think even a modest mining rig with a power of 500W would kill the compressor in the freezer pretty quick. The freezer would need to have the compressor running continiously, and they aren't made for that. It'd probably overheat and die in a week or so.
The compressors used in refrigerators will run perfectly fine at 100% duty cycle. However, the condenser, where all the reject heat is dumped, is sometimes embedded in the insulation layer around the refrigerator and is only capable of absorbing so much heat during a cycle. The fridge then radiates the heat away during the off cycle. Replace the condenser with a forced air finned variety and 100% uptime on the fridge is possible.

I watch a lot of Breaking Bad and Gustavo Fring uses these refrigerated trucks to distribute methamphetamine around the southwest United States while submerged in buckets of ingredients for the restaurants which he uses as a front for his drug operation. Imagine getting one of these refrigerated trucks and setting up racks and racks of cards/systems within the refrigerated box portion of the truck.
I realize that running the truck 24/7 may be costly in terms of fuel, but I've heard that..... there's this car.... it runs on water, man!
EDIT: Now that I think about it, as the result of a recent face off, Gustavo Fring is currently no longer using these refrigerated trucks, so acquiring said vehicles may be a viable option after all!

I know it sounds strange that the gpu's can get too cold. In my case it could be that the thermal contact between cooling heads and VRM's are bad at low temperatures because of thermal contraction. I don't measure VRM temperatures and I didn't investigate further. But others have reported the same thing.
well 95F wow, odd

about condensation: You could drill holes and seal them for the wiring, then fill the chest freezer with dry air or put in a few desiccant bags to have a humidity below the condensation point in there. But as you concluded yourself, the extra power costs makes it pointless. I have experimented with water cooling my GPU cores, and if they got below 35 degrees Celsius they hung after a few hours, so extreme cooling / overclocking might not be doable. Do anyone here know of anybody trying liquid Nitrogen on a graphics card?
thanks guys for serious commentary
Hmmm, Thats a thought, Because I'm in a "colder" country I don't have AC, So when I GPU mine it actually offsets my heating bill, But when someone in a hot climate GPU mines it costs them more in cooling, But I never thought about the freezer as crazyates said, The condensation is just too dangerous.
I'd be worried about wicked high electric costs, as well.
Plus, I think I remember someone asking a similar question a while back. They said the best bet was a chest freezer, where the cold air would sink and not escape as easily (cuz you won't be able to shut the door completely running your cables/wires into the fridge). Also, they mentioned condensation being a potential issue.
In general, I don't think it's a good idea. Just crank those ACs if you're that worried.

Same idea as using AC to cool your rig room. You would need quite a freezer and your electricity costs for cooling would be high. It takes a heat load of 3517 Watts 24 hours to melt a ton of ice i.e. if you would like to keep the air around your 3517W rig at 0 degrees Celsius.
Has anyone ever thought or tried to put their GPU mining rig in a fridge or freezer?
Obviously for purpose of max overclocking the cards
