Here some shots of the right side panel modded with a Bitspower Mesh Radgard
140mm and an extracting 100mm Fan (12mm thick) and 4 black Hex screws. There's a thin supplied anti-vibes also between the mesh and the side panel
Started the cutting round but it gave me not enough good results, so went square as the inside fan is round anyway. Will put a led or two later and might put a cover on the white backplate!
