INTRODUCING THE NEW H-SERIES


NZXT

The H400i 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. You can effortlessly 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 H400i's stunning tempered glass panel.

NZXT

SMART CONTROLS THAT MATTER

The H400i'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.

NZXT

BEAUTIFUL CRAFTSMANSHIP

The H400i 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.

NZXT

ENJOYABLE BUILDS FOR ALL

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 H400i layout ensures you'll enjoy building your PC as much as you enjoy gaming on it.

NZXT

STREAMLINED COOLING

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.

*Case version fans and specs vary from retail version.

NZXT

MODERN STORAGE

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.

NZXT

ADAPTIVE NOISE REDUCTION

Our unique Adaptive Noise Reduction uses an on-board noise sensor to measure and learn the specifics of your system to find the ideal balance between fan speed and cooling. With up to a 40% reduction in fan noise level, you won't need to waste time designing custom fan curves. Leveraging machine learning to improve its results, this will ensure your fan settings are always optimal, even if you change hardware.

Excellent case, High quality

Pros: Includes already cable managed backside and smart hub
Solid steel construction
Minimalist case and good airflow
Lots of great features like SSD mounts, PSU shroud, and built in RGB strips

Cons: QC for the RGB strip (not the already premounted one) needs help, 1 was dead on arrival.

Other Thoughts: For the price I'd recommend this case for sure

Exceptional Quality

Pros: - Built with high quality materials. No cheap and fragile plastics. Wiring and overall structure seems thick and strong
- Great packaging prevented any potential damage while being transported
- Awesome included documentation
- Fantastic quality control

Cons: - Not the greatest airflow

Other Thoughts: Concerned about the temperatures in the case, I decided to upgrade to a Corsair 900D, which is absolutely monstrous in comparison to the NZXT. That was a mistake! The Corsair is pathetically assembled and is made of the cheapest materials I've ever seen in a case. Corsair should be ashamed of themselves. They've lost the edge. It's clear that NZXT has improved over the years.

Great case minus the smart controller

Pros: mATX perfection. Good room and relatively easy to work in for a mATX case. Solid construction, nothing cheesy about this case.

Cons: The smart controller is a bit of a dud. It will not work with NZXT RGB fans. You need a HUE controller for that which is bullocks IMO. Anyhow, the controller has some good fan expansion cables you can re-use so just toss the controller and use your motherboard's lighting controls. But, if you install some NZXT RGB fans, which are very nice BTW, you will need the HUE controller to make it function.

Other Thoughts: Controlling everything through the the motherboard control and app and works well. Just need to get a HUE controller to run the NZXT RGB fans I installed. Good fans, quiet and decent CFM but no lighting without the HUE box. Motherboard used is the MSI Z370M GAMING PRO AC LGA 1151 (300 Series) Intel Z370 HDMI SATA 6Gb/s USB 3.1 Micro ATX Intel Motherboard

4/ 5

Pros: Really good looking case.
Holds a full size 1080 gpu.
Mostly easy to build.

Cons: The 3.5 drive mounts are in real awkward spot.
The smart case that controls the case's LEDs don't seem to work for the LED fans.
The glass gets finger prints easy.
