PowerColor 4870 1gb + Antec 300

Hi all!

Im on my final steps on biulding a new gaming rig

I've been reading about the heat issues with this card that depends in the ventilation of the case

I was wondering if anyone know if the powercolor 4870 1gb version goes ok with a antec 300 case?

i know the card is big and it would bother the hdd drives, but im geting one hard drive and one gpu, so maybe no problem with that..

what about the case air flow for the card? the case comes with a back fan and a top fan.. maybe should i add one or two front fans or maybe a gpu fan like this one:
