The innards of my keezer project. 7.1 cu ft kenmore just fits 4 kegs. 3 full 5 gallon kegs plus a smaller 3.5 gallon keg and the C02 can on the hump. Currently have a 2 valve C02 system with "soft" manifold (T splices) - 1 circuit has a single connector an dedicated valve for carbing at high psi; the other circuit has 3 connectors T-ed into the second valve for serving pressure. I did the soft manifold just to experiment with my needs. Because I have different beverages (brews, sodas, ginger ale, ciders, etc.) dedicated valves or regulators may be the way to go....but too expensive for me at the moment!
