Most people bend the freezer down on dorm-fridges because the kegs are too tall to slide in underneath it.
But, then again, most of the dorm-fridges people use for kegerators are only 4.5 cubic feet. You've got a lot more space inside that one if it's 6 cubic feet, but based on the dimensions listed for it, it's the same height as a 4.5 cubic foot fridge, so it must be wider or deeper.
pinlocks are a little shorter than ball locks, so you might be able to get a couple of them in there without having to mess with the freezer.
