The front of my PC-75 Lian-Li has 2 80mm intake fans but they are pulling air though a bunch of little holes in the front of the case so I was thinking I should use a dremel or some tool and cut out a big rectangle and put some kind of cool looking mesh or something that will improve airflow. When I feel the air the fans are blowing and pull the front off I can feel it incrase by a fair amount so I know this will make a big difference. What should I use to cut it and what should I use to cover it. Maby just drill 4 holes for each side and put one of those cool lazer cut fan grills on it? Im kind of worried about cutting it because ive never really modded a case before and I dont want to wreck the front of my case because I dont know where to get a new front. Also If i cut it out and use some kind of sanding attachment in the dremel to smooth it out how would I get the corners to be good?
