I have two friends that built an insulated enclosure and used a fridge to cool the enclosure. A very simplified
description is they build a walk-in cooler with a door and a hole. The hole is an exact match to a fridge. the
fridge has its door removed and the unit cools the entire cooler. No reason why you could not to the same
but scale it down...use a dorm fridge to cool a box the same way...
