Large Proofing Box from a Broken Fridge or Freezer?

Large Proofing Box from a Broken Fridge or Freezer?

Looked around a little here (but not a lot) and was wondering if anyone had any experience with making a proofing box out of an old refrigerator, working or broken. It seems an obvious solution to creating a large temperature-controlled environment. Much of the same stuff used to make smaller proofing boxes could be adapted to this solution. 

A working refrigerator could be outfitted with the sort of on/off thermostat that people use for brewing, and perhaps some sort of humidity control could be added?

Thanks in advance for any leads on other who have done this.
