If that's what you're wanting, I'd say just get a used fridge off Craigslist, drill holes for taps, and use the freezer compartment for hops. It's multipurpose and you don't need a temp controller. That'll be my ultimate kegerator. Right now, I have a chest freezer with a sweet collar on it and use the compressor hump for cold crashing carboys. I like it too, but the fridge setup is what I'm really wanting someday.
