Using the smallest ones of these:
and a bunch of these:
I have my 10' lines for my kegs, my reg setup, and my CO2 lines all zip tied neatly to the lid of the keez. Everything swings up and away with the lid, so it's easy to change kegs.
The beer line and the gas line are also zip tied together and numbered, so it's easy to tell which set of lines feeds which tap.
When I add the other 3 taps, I'll be mounting the CO2 and the Nitro tanks outside the keezer. I'll use QD's through the wall of the collar. I'm adding a fan to equalize temp and control some of the moisture inside.
Once The guest is out of the spare room and I can pull the keez out I'll take a pic of how it is now.
