You haven't given us your budget, so that makes it very difficult to suggest components.
Mobo : The Asus board that Punk linked looks good enough. Much more featured than that Intel one at a better price point. I don't have a particularly bad experience with Intel Mobos, but most people here will tell you that they're crap.
Technically, you won't need any case fans whatsoever, but they won't hurt either. This - COOLER MASTER HAF 912 - should be good enough for all your needs. It comes with 3 fans as standard and you wont have to worry 'bout buying any more. And don't waste your money on any aftermarket cooler either. When you'll need one, you'll know it.
Go with the GTX 460 (I have the EVGA 1GB model, non-overclocked). You'll be ridiculously happy with it. Check the combo deals for the video cards; you'll get Just Cause 2 from Newegg and Metro 2033 from EVGA. Pretty sweet deal if you ask me.
