The build suggested above has a power supply that's way over kill quite honestly with that rig, you'll draw at the wall (not at the PSU) under 300 watts. The case is personal preference, that's why I choose the Arc Mini R2, I own one and it's a beautiful and well built case.
Now let's talk about the video card. I suggested a 970 because I don't know what resolution you're gaming at. I'm assuming you're gaming at 1080p, which is why I suggested the 970. The G1 is considered the best model of the 970 series by almost everyone. Check on Overclock.net you'll see (you can message me there too if you have any questions).
If you're gaming at 1440p, I would suggest aiming for a 980, which still fits into your budget. You also have room to spare for a 500GB SSD and larger HDD if you wish.
I'd be gaming at 1080p. I guess in the near future 1440 once I upgrade monitor to that but for now just 1080. I'll check out ur build.. I have a psu on my current pc that's 650 or 600w so I might be above to save 100 on that possibly
