Plenty of room at the top for an airlock. The fridge is a standard under counter beko. Heater in the bottom, inkbird temperature controller.
The one slight surprise was just how heavy (and ridiculously over specced) the valve is. I wish I could find something slightly more appropriate. Angling it like shown makes it easier to close the fridge door - the handles are really quite long. When I was researching it was hard to find photos of fermenters in fridges so I'm posting this in case it helps anyone else make the decision.
