however, as of now, it is out of stock, you could try other websites, like amazon for example.
PSU: the power supply you posted is cheap. A $1000+ system should have a much better PSU, at least a bronze plus certified, and modular (not necessarily fully modular) for good cable management which implies good airflow.
Reliable Manufacturers are Corsair, Seasonics, etc.
Since you are not overclocking, the stock fan that comes with the cpu should do fine. Drop it if you are tight on budget. Also, the i5 3570k, the "k" is for people that wish to overclock, you can drop your price by buying the non-k version: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
One more thing, why not use the onboard sound card, are you setting up speakers to fully utilize that 7.1 sound card? Otherwise, I'd just stick to the onboard one and use a 7.1 headphone.
the extra fans aren't needed since you aren't overclocking your cpu and really depend on if you're going to be gaming for long periods as your GPU will heat up your rig after awhile. What he said above about the PSU and SLI and Crossfire are for when you're using 2 nvidia GPUs (SLI) or 2 amd GPUs (Crossfire)
