Well, I'm currently using a rosewill challenger and it's a tight fit for my radeon 5770 and I'm not getting good airflow due to it. I want to upgrade to a bigger case that will give me better air flow. I have 5 fans currently set up in the case and my GPU still reaches around 65 Celsius when under a heavy load. My CPU gets up too about 35 Celsius but I want to put a decent size aftermarket cooler, just because I like my parts to be icy. Right now my 5770 stretches from about the hard drive bays to the end of the case. So any suggestions would help. I prefer not to spend over $100.
