Case Airflow Tips

[arya]

I'm buying this case

Flash Demo

It has 1 - 80mm on Top

1 120mm - Side Panel
1 80mm - Side Panel

There are two more slots for fans

front 80mm
rear 120mm

As i dont have the case right now I cant tell which fans are for exhaust and which ones are for Intake. I'm not aware of CFM of these fans.

Here is what am gonna house in there.

P5B dlx / P5W DH
E6600
Gskill 2x1GBHZ
XFX 7600 GT

What will you guys suggest me to do, add extra fans or not? And in which way to keep the fans?

thanks
