I bought a wine fridge at one time, about the size of a dorm fridge, but the hump allows me to place my buckket or carboy on the bottom, in front of the hump. (So there is plenty of room for two kegs). It has a glass front, and when I am not fermenting in it, I put a few cases of beer in there.
One thing to note, the original thermostat in the fridge only went down to about 50F. I replaced the thermostat with a Johnson, and I can get down to 35F now with no problem.
The brand name is an "ewave" and I got it new for about $125 to $150.
