what's the conventional wisdom on which way fans at the bottom part of the rear of the case should blow? I thought all inflowing air was supposed to come from the front and all rear fans should exhaust out. But I've seen a lot of diagrams which have the bottom rear fans blowing in, too. This makes sense in that the cooler intake air at the bottom is expelled at the top. But I wonder if this setup would interfere with overall airflow.
