I got a small chest freezer (about 25"x25") off CL and put a 2x8 collar on it. The hump is in a single corner and without the collar thee kegs (any type 5 gal) fit. I wanted to use the hump so I put the collar on. Now four kegs of any type 5 gal fit inside. I have 20lbs tank on outside with manifold on inside. Also added a 120vac fan in a corner to move air when it's on. Only three taps on it right now but plenty of room to add a fourth.
