I was wondering if one of you would be kind enough to measure the distance from the front of the front foot to the back of the back foot. I'm hopefully I'll be able to pick one of these units up used and am curious if I'm going to have problems fitting it in my equipment rack. I know width and height won't be a problem. But the unit is 19.5" deep and my component racks shelves are only 16" deep. I don't care if it sticks out the front or back at all, but I am hopeful that most or all of the feet will still be on the shelf.
