Product Overview

The H9 Flow RGB (2025) is NZXT’s flagship dual-chamber mid-tower, offering exceptional cooling flexibility and a striking wraparound glass aesthetic. The dual-chamber layout places the PSU in a separate upper compartment, keeping the main build area uncluttered and improving thermal separation. The pre-installed F420 RGB Core covers the full side chamber intake as a single-frame 420mm unit, with the F120Q handling rear exhaust. Radiators up to 420mm are supported at both the side chamber and top positions simultaneously, making the case well suited to dual-loop or high-capacity AIO cooling setups. GPU clearance extends to 459mm with standard fans, or 410mm when using a 56mm thick 420mm AIO. Back-connect motherboard support is included as standard.
