There are three kegs connected, serving a Witbier, a Christmas beer and an Oatmeal Stout. The fourth tap will have to wait a little as I'm missing a gas quick disconnect. I don't know why it got lost. The flow rate and carbonation levels seem to be quite alright, except that I seem to be having a leaky keg leaving the Witbier a bit low in carbonation. I tend to close the CO2 tank when the kegerator is not in use, just so that I don't end up with an empty tank without wanting to. I'll have to take a closer look at the keg to give it a better seal. A little lubricant and a tighter lid might help.
Much of the challenge of designing it has been to get hold of all the necessary pieces so that it would actually work. Below you'll find a list of all the components that I used. I bought the equipment from MoreBeer and Brewers Discount.
|1x||D1413 - Drip Tray - 13" Wall Mount||$49.00|
|1x||D1810 - Gas Manifold - 4 Way||$47.50|
|12 ft||D1704 - Beverage Line (5/16 in. ID)||$7.20|
|16 ft||D1700 - Beverage Line (3/16 in. ID)||$8.00|

|4x||BL010-1-QD Liquid 1/4" MFL||$15.00|
|9x||H011-Swivel Nut and Stem 1/4"||$14.85|
Total cost: USD 288.50 (plus shipping and VAT)Hopefully the list is helpful and that it might help you get started on your own kegerator.
Update: After rechecking the setup I realize that it is a ninth swivel-nut and stem that I am missing, and not a gas-in quick disconnect. The reason is that I had to use one to connect the gas line to the CO2 regulator. I've updated the costs above accordingly.
