I'm looking to get a "mini" fridge to house a 5 gallon keg, and all the necessary equipment. I've found one on craigslist that has these dimensions: "MEASURMENTS 32 HIGH...18.5 WIDE...19 DEEP" I would have to tap into the top of it however to make it a typical "kegorator" style, will that even work, or will I need to start with a standard refrigerator?
