I had been thinking about getting a water cooled case, but figured why not just use a freezer. It costs about the same or less.
A fridge/freezer costs about $100 & a small Dehumidifier is only $50 + maybe $20 bucks for a hygro-thermometer.
Has to get the chip etc colder than a water-cooled case.
Probably would have to raise the temperature of the case before I shut down the system so nothing would break from the rapid temperature change. While I haven’t given this a lot of thought, it seems fairly doable.
