if you put the 80mm fan in the top, do what i did and put two side by side, looks much better and the fans dont looks as out of place as just one does. also if you can use old fans, do, they are often much better quality, ones i found in some old power syupplies been working for 10+ years and still move lots of air with little noise. (would post a pic of my 8 year old modded case with the fans in the top but i can never get images to work on this website. and i hate photobucket. but its just simple black fans in a simple black case, i plan to add some either darm blue or dark red cold cathode lights as well, maybe add a new hole for front panel 80mm fan. (under the one that is already in it) and possibly one up higher in the optical drive cage, there is lots of stuff you can do with computer cases, but you might want to start with a different one, sometimes the simple looking ones can be the coolest after modding.
