From SilverStone, KL04 and TJ04-E are two tower cases that you can consider. Both were designed for positive pressure and with easily removable filters on nearly all sides.
Thanks. I'll take a look at both.
The TJ04-E is certainly different. I'm not sold on the idea of drawing in air from vents in the top of a case. Dust naturally settles down, and warm air naturally flows up. In addition, there is the risk of a hot air loop from the exhaust on the top rear getting pulled back into the case through the top vents. If there are vents in the top of a case, I'd prefer those to be used as exhaust vents.
On the TJ04-E, you could always reverse the fans on the top, but then you will need to increase the speeds of other intake fans or add more intake fans to compensate and restore the positive pressure. Before you know it you've got 7 fans running.
It seems to me that positive pressure would easier to do in a case that has fewer vents in general, and could be therefore accomplished with fewer fans in general. I want to make sure I'm getting air flow over the logicboard heatsinks surrounding the CPU. With air exiting the case in multiple locations, it becomes more of a task to direct airflow in a specific area.
I think if I got the TJ04-E, I'd be tempted to seal off the entire back panel and use only the top vent for exhaust, which is probably the opposite of how the case is designed to work.
At the moment, my favorite is the Antec P280, though I still really like the Solo II.
