[Waters]

I've seen some that habe both holes to screw the fans in and/or a box similar to that. Usally, with such a box, you can just stick the fan in there without any screws or anything

try unscrewing the box, set the fan in the box, and screw it back in, that looks plausable

Check the rear panel of the case for tabs connected to that box that can be squeezed to pop it out of place. Drop in your fan, connect it, snap it back in, tool free.
