I am getting ready to re-model the basement complete with an underbar kegerator. I would like it to be capable of both comercial kegs, or homebrew (I've never kegged before since I don't yet have the equipment.). Is there anything in particular to look out for on the kegerator to make sure it will accept a home keg? Also, how many Cornelious or similar kegs would I be able to fit into a fridge that is designed to fit a 1/2 barrel?
