My case is the Rosewill Blackhawk and has a slot for a fan on the bottom as well as two on the top. I currently have one mounted on the top blowing air out. I am torn between putting the bottom one in as an intake or output... I don't want it to just be sucking in dust off the ground while at the same time screwing with the airflow too much. The GPU fans do point down towards it which could be another reason to have it as an output. What do you guys think?
