I have an Antec Performance Pro, which is based from the same case that you are buying.
Currently I've got three 80mm antec smart fans (came with the case) blowing air in (1 in the lower front purple bracket, one in front of two HD's), and one in the side panel. In the back are two 80mm 32CFM coolermasters blowing out (from the purple brackets) and some air being sucked in from the PSU's bottom and blown out the side (man is that air hot).
I'm pretty satisfied with the coolermasters. They look great (4LED's), and push a decent ammount of air, and are quiet.
The SmartFans on the other hand can't seem to push enough air., which kinda sucks because I'm relying on them for intakes! There is only one that works decent, and that is the side panel one connected to it's own dedicated molex adapter. Just a few minutes ago I hooked the lower front smartfan up to it's own dedicated molex adapter (forgoing using the PSU's weak 5v dedicated fan molex's) and it only pushes a little bit more air. I think that it just doesn't have enough power to really move air into the case, or that the temperature sensor on it is fubar'd.
I'm doing some research right now how to disable the temperature sensor, because noise really isn't an issue over one of my rabid HD's (borrowed it and it's louder than any HD i've ever owned, just sitting there spinning)
If I were you, I wouldn't go with the SmartFans. In general I like Antec's products quite a bit, but the SmartFans just don't have the balls to do modern cooling. Check something with more CFM and also importantly make sure it has a high pressure level, since that will aid in sucking air through your front bezel (if they are in the front) or pushing air farther away from the case (and potentially from a larger pocket of hot air inside) if they are exhaust.
Those are just my two cents. If you want to buy some smart fans I've got three to sell. (With shrink wrapped wires too!)
