H400i Micro-ATX Gaming Case - White Tempered Glass

The H400 showcases NZXT’s vision for modern PC building. This premium micro-ATX case features a unique CAM Powered Smart Device that digitally drives RGB lighting and fan performance. It empowers builders to easily control RGB lighting and fans, while Adaptive Noise Reduction optimizes your build’s acoustics through machine learning and ideal fan settings. Includes three integrated Aer F fans and two RGB LED to enhance the aesthetics of your build as seen through the H400’s stunning tempered glass panel.

The H400’s unique Smart Device includes features from our HUE+ and GRID+ V3 digital controllers, allowing for effortless control of RGB lighting and fans through CAM software. Customized lighting is streamlined with two integrated and individually addressable RGB LED strips. Don’t waste time checking compatibility, installing, or manipulating physical buttons; our out-of-the box, elegantly controlled CAM software is all you need.

With up to 40% noise level reduction, there’s no compromise between system cooling and silence. CAM’s Adaptive Noise Reduction learns the specifics of your system and adapts as your PC configuration evolves. Machine learning ensures your settings are always optimized for the best gaming experience possible.

The H400 is available in four color combinations to match your taste, and its elegant all-steel construction is shared across all sizes in the new H-series. The tempered glass panel and signature PSU shroud showcase beautiful builds. Cable management can often take more time than assembly. We designed a new cable routing kit with pre-installed channels and straps, on the back of the motherboard tray, for intuitive and easy wiring. We also upgraded our signature cable bar to be adjustable. The H400 layout ensures you’ll enjoy building your PC as much as you enjoy gaming on it.

We simplified water-cooling installation: a front drop-in bracket is designed for radiators up to 280mm, and integrated reservoir mounting for custom-loop systems. Three Aer F 120mm fans* are included for optimal internal airflow. To preserve your system’s clean looks, front and PSU intakes are fully filtered. Storage installation is a snap with the single, quick-release 2.5” SSD tray positioned on the PSU shroud. There are also two steel trays behind the motherboard with an additional 3.5” mounting below the shroud. This storage layout optimizes airflow and interior space for a clean-looking build.
