Product review (5 stars): Perfect Kegerator and Fermentation Chamber
I own two of these now, and I can't say enough good things about them. Both fridges are extremely quiet.  One is serving as a dual tap kegerator, and I later bought a second one to use for lagering. There was literally no modifications necessary to use it for a fermentation chamber. It's plenty big to fit a 6.5 gallon glass carboy with 3-piece airlock, or two 5 gallon corny kegs. I use the gas tube hole to feed in the temperature controller's probe. It's also on casters, so it's easy to move around when full.
