I have an NZXT Phantom 410, so I'm pretty familiar with the brand.
The NZXT H500 isn't the best series in terms of breathability, but it should be fine on stock settings (if you did get the case, I would buy a couple fans to put behind the front panel, there's a couple slots there).
If you were planning to overclock, I would consider looking for a case that has 2 fan vents on the top instead of 1 and/or a case with a vent on the front to help pull in air. NZXT's cases rely on the top and back vents to let out heat and the front, buttom, and sometimes side to pull air in.
Tip: You might find a little difficulty managing cables with the H500 just so you know.
Hope I was helpful!
