NZXT H2 Flow (2026) Mini-ITX Case with window, Black

The NZXT H2 Flow is a small form factor PC case designed for Mini-ITX motherboards, occupying a total volume of 20.7 liters. Its internal layout is oriented vertically, intended to display the graphics card prominently through a tempered glass side panel. To facilitate this build style, the case includes a PCIe 5.0 riser cable for vertical GPU mounting. The primary construction materials consist of a steel frame and tempered glass panels, with an integrated dust filter to maintain internal cleanliness.

Thermal management is addressed through support for various cooling hardware configurations. The chassis can accommodate a front-mounted 280 mm liquid cooling radiator or multiple air cooling fans at the front, top, and rear positions. Component clearances are specified at 75 mm for CPU cooler height and 130 mm for SFX or SFX-L power supply length.
