  There are at least two versions. One is the white square box about 13"
square and there is the older model that was in a biege box that was about
17" wide and the ends were rounded. As I recall it had vents in the front
and rear. You don't see the old version very often but I have a couple of
them here. I think there were also a couple of different versions of the
unit in the new style box.
