I was looking into mini fridges for my kegerator. Then I read a lot more on freezer conversions. HD and Lowes both had huge deals on their 7cf chest freezers. $159 with free shipping. That will hold 3 kegs on the floor loosely or 4 with a super tight fit with 1 on the hump as well as your 5lb co2 tank. With everything ordered including all the hookups, line, faucets, shanks, etc, I'm in my keezer for just under $500. You can obviously do this cheaper by not spending $160 for a new freezer and get one off craigslist. It depends how much you want to spend and how much space you have. Limiting space, mini fridge with towers work nicely. A bit more space, can't go wrong with a chest freezer IMHO.
