Switching cases, temperature question

[Dorkenstein]

I'm going to be switching from an Antec Twelve Hundred to a Silverstone Fortress soon. The Twelve Hundred needs to be cleaned all the time with all its fans. Not a huge deal, really. Also, I find it hard to rout the cables around in it. When I get the Fortress, I have only one concern. The Twelve Hundred keeps things really, really cool. I don't have an exact number for temperature but the air it generates makes my feet and legs really cold sitting near it.

So I'm wondering, what kind of air flow does the Fortress get? I'm guessing it will be less airflow and thus higher temps, but does anyone else here own one that can give me an idea? Thanks for any help.
