If you can find a good sized mini-fridge, go for it. The problem I have found with a lot of them is that you will most likely have to take off the plastic shelving they put onto the door as you lose about 4-6 inches there, and most are not just a large, empty rectangle, the bottom usually compensates for the compressor, and you lose half the space in the bottom of the fridge. Most larger min-fridges also have small freezers, and you have to deal with them. So it can be difficult to find one to fit your dimensions. If you have the room--try to get a full-size fridge. Then you can also use it to keg.
