[View 71 Top Glass]

Greetings, I have a 240 AIO for my GPU up top of my View 71. It is set up with push pull fans. I removed the dust filter and dropped my temps 4 c. I would like to raise the top glass panel a 1/2 inch or so to gain more airflow. Has anyone else done this ? I would like to keep the top glass panel but it seems I am recirculating some of the hot air back into the case and thus threw the RAD in this current config.
