Much better build than the other one linked, but pick your own case, you can pay as much as you want for one and that's your own preference. I'd advice against the case I linked, it's probably really bad. I really like the HAF cases and corsair ones and would reccomend them but go with what you think looks cool
TC I have the exact same video card you showed in your first build. I am very happy with it, it has been able to run all my games at 1080p max setting 60fps.
As for the cpu in your build well if your on a budget it will be ok for now but may need an upgrade somewhat soon. If you can try to go another $100 and get an I5 and the equivalent MOBO I think it would be better for you in the long run.
O on a side note that video card is a bit big, so make sure you got the room.
