Product review (2 stars): Worth paying more for more size
This just barely holds two 1/6 barrels with the regulator and CO2 bottle inside. (note that the regulator MUST be inside if you use two hoses because only one hose fits through from the back) It really seems worth the extra cost to get the slightly-larger cabinets (Kegco 209 or similar).

Also, tall 1/6 barrel kegs (look like Cornies, but have Sankey coupling) will fit, but only with a low-profile coupler. So be sure you know the barrel size, or you will have to drop extra $ for the low profile (might be worth initial upgrade for one of the couplers, if you order on the Bev Factory site and customize).

You will need to add a computer fan to circulate air to keep the temperature steady and low (lots of instructions for this can be found on home brew blogs, and it saves cost of buying forced air fridge models). It does occasionally make cracking noises when cooling, but it's pretty quiet overall.

On a side note, Beverage Factory customer service has been pretty weak: no shipping notifications, very slow to send replacement parts, and failed to send necessary parts when they replaced a broken elbow shank from my original order. Keyworks or Micro Matic are probably better options from a service perspective, but might cost more and don't sell the cheaper refrigerators/cabinets.
