Building First Computer through Amazon

You don't need a network adapter, pretty much all motherboards have them integrated now. You could probably get a 2500k, unless you are doing heavy video editting, and a spinpoint f3 would be a better choice than the WD Black
 
That ram is really expensive and it would be better to just have two sticks of ram and not three. Having two sticks will allow you to add more ram latter on, and the ram would run in duel channel mode.

You may also want to look into getting an OEM version of Windows 7 Pro. An OEM license can only be used with the motherboard you buy and can not be moved to another computer.

Do you plan on overclocking? That CPU cooler is big.
 


Shouldn't I have a CPU fan? Would you recommend any other cooling setup?
 


Thanks for the advice, Someguy!
 


The i5 comes with its own cooler right in the box with the CPU. If you really want a good-looking cooler, go right ahead and get one, but I was only saying save the money on the cooler and put it toward a better video card, which is the one place you'll see the most improvement.
 
It would be hard for me to justify spending that much on Windows Office. While openoffice is admittedly a bit worse, it is free! You could spend that money on a 128GB SSD (crucial m4 or what not). I like the changes to the rest of your purchase though. The GTX 570 will be great for most games now and you could always upgrade to an SLI setup later.
