After using my old setup for 6 years, I decided it was time for an upgrade.
I narrowed cases down to the Corsair 570X and the NZXT S340 elite; I chose the 570X once I saw it in person, such a beautiful case with all the glass. I decided to stick with Corsair as much as possible to be able to sync all the RGB and it doesn't hurt they make some top notch products.
I mainly use my PC for gaming so I chose to go with the i5 8600k instead of an i7. I originally wanted to get a 1080 ti, but I can't bring myself to pay that much for a video card right now and the 1060 I have runs the games I play well enough. The H115i pro keeps my CPU cool while gaming, it never goes above 50c and is pretty quiet.
Overall I am happy with this build and enjoy it.
