It doesn't exist anymore, but yeah, good call. I never replaced it once the batteries finally gave out, and I moved less than a year later.
It did have vents on the sides for airflow, but that was more of a consideration for heat build up and keeping the controller from cooking in the summer. It was also less a "box" and more like a small doghouse (including shingles lol). I atually gave it to a neighbor after I was done with it; they cut a hole in the door and used it as a cat house.
