I just got an AOI water cooling system and am trying to mount it to my case, but the directions make it look like I need to place the radiator on an inner wall in the case and screw it on my screwing a screw from the outside of the case, through the case wall and into the radiator. But since I don't have any holes that go all the way through the wall of my case, I'm wondering if it's ok to push the screws through the mesh/fins of the radiator. Would that cause any issues?
