Since no one seems to have asked yet, do you happen to have a
microcenter nearby? They have fantastic MoBo/CPU combos if you do.
In terms of parts, I would say that Kostattoo's build is pretty good, but I would definitely drop the i7 down to an i5 4690k and overclock it, as it'd be a waste not to, and it'll give you similar performance to the i7 unless you plan to start streaming. Getting a slightly cheaper Z97 MoBo and a different case are also options, though those more boil down to personal preference.
