Thanks for sharing that information. The kegerator would be going into a conditioned space; therefore, sweating would be less of a problem. Many of the homebrewed kegerator builds that I have seen use insulated copper pipe to keep the hoses cool in the tower. I do not know effective this technique is or how much it cuts down on sweating, but it has to be better than doing nothing at all.
I have always kept my kegs in a standard refrigerator. I use picnic taps, so that I can clean the keg and the tap at the same time. My CO2 tank connects to the refrigerator via a bulkhead fitting and a ball-lock gas plug. I have a gas manifold with shutoff valves inside of the refrigerator. It's a simple setup that is easy to maintain.
With that said, can one store four ball-lock kegs in a BM23? I am looking for additional cold conditioning space as much as I am looking for a kegerator.
