caledbwlch said: I’m running a core V21, but I keep the panel on the side so heat can rise out the top, and to keep it from getting dusty (I can’t imagine the plastic will hold up well to repeated wiping). That being said, it won’t cause any significant issues. That case has tons of airflow. If you add a 140mm at the rear (right by the processor too) you’ll be in even better shape. So in short, having the panel on top will be fine. My issue is that the cable management below can be ugly, as some reviews said due to the long cables by the I/O. Also you mentioned that you’re concerned of the plastic holding up to repeated wiping. What do you mean by that? Do you think the window panel will bend if you put enough constant pressure due to wiping on it?
