I would suggest getting a 3rd party heatsink/fan so that you have the option of OCing without worrying about getting too hot. I personally am favoring the Thermaltake Big Typhoon due to its extreme quiet as well as great cooling and low price.
Also get some Arctic Silver 5
Another option is the Zalman CNPS9500 which is also a great heatsink/fan but is a little more costly.
Other than that looks pretty good to me. I don't know a whole lot about that MOBO, have to get someone else's input on that. One question would be what Power Supply will u have? I believe if you get the Antec Case like the one I got that is in my sig a good 500w Power Supply comes with it.
Edit: I forgot do you have a decent monitor to show off this other nice hardware you are getting? My monitor was one of the most pricey things on my list of hardware when I built this comp
But now that I have it I stroke it and love it every night.
Oh ya and if you are ethically challenged like me you might skip the operating system
