I have the antec 1200 and i was going to add 2 more fans to it. I am pretty good at drilling and all just was wondering what fans would be good and where in the case would be a good spot? i was thinking possibly 4 fans, 2 extra in side and 2 extra down below. just by adding wheels so it would be lifted so i can add to below fans. any advice on size of fans and would this be a good idea?
