Thanks guys. This does span two stud bays, so I did have to put in a header when I cut the stud away. I didn't mess with the internal thermostat because I like the ease of the controller. Before summer rolls around, I will insulate the pvc pipes. The tiny fan I got moves a lot of air (31cfm) and does a great job at keeping the faucets cold. I originally had it mounted in the same box as the taps but the noise was too loud in the kitchen so I moved it into the keezer.
I really need to get a drip tray on this thing. I was thinking about getting the Bar Products drip tray and cutting it down to fit (my space is 18" and the Bar Products tray is 19.5"). Anyone have experience with that tray?
