What case would be good with this build?
I have a few cases in mind:
Great build quality, lots of compatibility and one of the best airflow cases in the business.
Both very straightforward, simple cases but they have good build quality, compatibility although they restrict airflow a bit due to a closed front panel. The H500i, should you be interested, comes with an integrated RGB/fan hub and an RGB strip.
Awesome build quality, looks great (IMO) but also restricts airflow a bit. It's kinda built for a 360mm radiator/AIO so it may look weird (like my build) without a radiator in there.
If you're feeling fancy and have the funds, this is a very aesthetically pleasing build (again, IMO) and offers everything that a premium case would. This would require that you switch to micro-ATX
Fractal Mesihfy C or S2.
