Build looks good, and of course all of the advice offered is good.
One thought -- if you have any thoughts of adding a second graphics card down the road, you might consider getting a 1K w psu or higher. In my experience, the psu is a good place to buy with overkill in mind as it will save you money replacing it down the road. In other words, spending a little more now to "future-proof" you psu choice will save you hundreds of dollars a year from now when you decide to grab a second 680 for $100.
p.s. yes, I know my psu is only 850w, but I've hit the ceiling of what it can do and now have to seek an upgrade.
