I think the ACF7P comes with a stock 120mm fan already.
They should be cheap though, like you can get a decent one for $10.
Consider that there's over $130 difference between the NCIX and DirectCanada builds that are pretty much identical, with the DC build having a little bit of an edge with a better psu, memory and heatsink. Well, just ask around and do more research.
Another thing is, if you have some patience, I'd wait for the Phenom X4's, 8800GTS V2 and HD3800 series, see what happens with them, and you can even wait a little until January 08 for the Yorkfields (Q9450 in particular) especially when it's going to be almost the same price as the Q6600 on release.
