I wasn't paying much attention when grabbing the case and just realised about its bad airflow after I assembled it. I also tried removing the plastic side panel before but keep worrying about the components being directly exposed to dust, etc. About the front panel, it has I/O ports mounted right on top and therefore I can't completely remove it and having it lying on the floor isn't an ideal solution. However, I think I can replace my radiator with a 360mm one to give more breath to the case. Thanks a lot
