Here's my addition to the DIY collection.
First I removed the lid and sized it up for how many kegs it will hold. Then I cleaned it up. It can hold up to 8 corny kegs.
Next I built the collar out of some 2 X 6 that I had lying around and stained it.
I then attached the collar to the freezer using construction all-weather glue. I then sealed it with a silicone sealant.
For now I'm just using 4 ports. I offset the taps so they weren't in the way of lifting the kegs in and out of the Keezer. This gives me room to ferment Lagers or do a cold conditioning after ferment. I'm using the analog temp controller and it's all working great.
