Had one
several years ago. (Damn, wish I had a pic of it) It was a square sided box that I painted flat black. Found a company that sold the decals they use on safes, put 'em on and a friend fashioned a combination dial on a wood lathe for me. When finished it looked just like a large safe. Put an inter door in it that held the beer dispenser.
Wish I had it back....
