Mine is about 2' from back of fan to front breast, 3' 1" to top of fan, and 2' 4" wide with the fan being the widest part. It stands on a oblong base that sticks a little in front of it and a little behind it. Hope that helps. They take up alot of room, if I ever had another one done it wouldn't be in full strut. Killed a good one with 3 beards about 8 or 9 years ago and just had to do it.
Unless your gun case is like one of those huge fire resistant ones you might be hard pressed to get one to fit on top.
