Antec P160 vented enough for Crossfire?

[S-M-R-T]

I am looking at upgrading to a new system including an E8400, up to 3 hard drives and a Radeon 4870 (with the ability to add a crossfire a second in the future). I currently have a P160 case that I love but I am worried that the stock fans (one 120mm in the front and one 120mm out the rear) might not be enough to keep a hotter system like that cool. Are these concerns founded and if so should I just mod in some more fans or upgrade?

hum, how are your ambient temperatures? I think you should be ok, but you will have to turn up the fan speed on the 4870's. I still think things will get a bit toasty, though nothing out of spec.
