I plan on installing it in the keg leg og the L-Kegger. I think there is enough room to extend the line and install a spill tray on the serving surface of the bar. This would hide the top of the kegger but still allow for reading the temp.
It is a bit more than building one but a lot less hassle, the door seals (less frost build-up and probably more efficient. Remember it includes the CO2 tank, keg fittings tower and tap.
