This is what ShastyMcJasty said to me in a message...."As for the refrigerator, it was about 2x2x2ft. The pacing items are the compressor and the condenser. You want them both as small as possible. The height of the compressor is the main concern. Mine I believe was 6.5 inches tall at its tallest point. The height is very tight. Every step should be taken to keep the height to a minimum. When mines together I have less than an inch clearance between the lid and top of the keg."
