Honestly, you don't have a whole lot to worry about. I have a tuniq in mine and the intake fan blows DIRECTLY onto the tuniq so temps are actually pretty good regardless. I wouldn't worry about the hard drives being too hot because the exhaust fan is right in front of them so they get a good amount of airflow over them. When I checked last, my seagate 7200.10 320gb was running right around 30-35C. I really wouldn't worry about the reverse airflow. I really like it actually because now the case exhausts out the front instead of pushing it out under my desk like it used to.What are your thoughts on the reverse flow? I really dig this case, but the thought of my Tuniq belching off its heat into my hard drive kind of scares me. I was thinking along the lines of making it front to back, but then the exhaust of the powersupply would be getting sucked into the new 'intake' in the front. So hard to want small but always drawing the conclusion that heat=big case. Unless you guys can think of something better? Somehow water cooling with a top mount radiator in this case like is shown elsewhere in these forums seems like such a sweet idea.
