NZXT H6 Flow RGB Mid-Tower Case Black CC-H61FB-R1

Dual-Chamber Mid-Tower with Wraparound Glass

The NZXT H6 Flow RGB is a compact mid-tower case built around a dual-chamber layout that separates the power supply and storage from the main component area. Tempered glass on the front and side panels creates an uninterrupted view of the interior. It supports ATX, Micro ATX, and Mini ITX motherboards for a wide range of builds.

Airflow Limits of the Perforated Panel Design

Cooling relies on high-performance mesh and perforated panels rather than open grilles, so dust filtration is integrated but maximum airflow is capped by the pattern density. The top panel accommodates radiators up to 360 mm, while the rear supports up to 120 mm. Three pre-installed 120 mm RGB fans sit at the angled front-right corner, with space for additional 120 mm or 140 mm units at the top and bottom.

GPU Clearance Decides Compatibility

The single specification that determines whether this case fits a build is the maximum graphics card length of 365 mm. Cards longer than this will not install regardless of other clearances. The CPU cooler height limit is 163 mm and the power supply length limit is 200 mm, but the GPU measurement is the most common restriction for modern high-end cards.
