Welcome to the forums! I hope you enjoy building computers as much as I do.
Overall, very nicely done. Everything looks good...you're not underspending or overspending (in other words, you have a budget and you're spending it). My only suggestion would be to consider changing the PSU, perhaps the Corsair 600w
version. It's modular, too, but is about $50 cheaper. And that $50, coupled with the wiggle room you still have in your budget could get you an nVidia 780
. Just a thought.
Be sure you to post your results - I'd love to see some pics. I was eying that case so I'm interested how easy it is to build with it.
Hope this helps.
