I got one the other day. 3" depth, 20" X 6" core, with (2) 3" tanks. That will let me be able to leave an inch between the IC and the radiator and shave off up to the end of the black grill. For those wondering, it's 4" exactly from the radiator to the end of the black grill. The black grill (opening) is also about 3.5" high. I still have no idea how to mount it, but I'll let the place doing it worry about that.
