Just finished my haf 912 build. One problem I'm having is that the lock for the 5.25" bay doesn't seem to work. Even in the lock position it slides back and forth a good bit. Also, even in the furthest up position, it sits back about an inch so it does not line up with the front of the case leaving a big gap. I can imagine this wouldn't be good for letting dust in.
Anyone else have this problem? Bad lock? Should I try the bay beneath it? Could I move it up to line with the front of the case and screw it into place?
