Small-form-factor PC builds are no longer an afterthought. NZXT’s latest releases—the H2 Flow Mini-ITX case and the C850 SFX power supply—prove that even the most compact systems can deliver pro-level performance without sacrificing airflow or expandability. These components, unveiled ahead of CES 2026, cater to builders who refuse to compromise on power, cooling, or aesthetics, even in the tightest of spaces.
At the heart of the H2 Flow is a radical rethinking of vertical Mini-ITX design. Unlike traditional cases that cram components into a shoebox, NZXT’s approach prioritizes airflow while shrinking the footprint to just 20.7 liters—smaller than a standard sheet of paper. This isn’t just about fitting a system under a desk; it’s about ensuring that every watt of performance is paired with efficient cooling, even when running high-end GPUs or liquid cooling setups.
Connectivity and Cooling Redefined
The H2 Flow’s standout feature is its all-around fine-mesh panels, which filter dust while maximizing intake and exhaust airflow. Combined with pre-installed F120Q fans and tool-less assembly, this case is designed for both ease of use and long-term reliability. But the real innovation lies in its support for graphics cards up to 331mm and 280mm AIO liquid coolers, making it one of the few Mini-ITX cases that can handle next-gen hardware without compromise.
For power delivery, the C850 SFX PSU sets a new standard for small-form-factor builds. With a 600W output and 12V-2x6 connector, it’s built to support the most demanding GPUs without adapters. The inclusion of ATX 3.1 certification, 80 Plus Gold efficiency, and Cybenetics Platinum-rated components ensures stability, while a fully modular design with embossed cables keeps builds tidy and airflow-optimized. The PSU also features a 92mm fluid dynamic bearing fan with Zero RPM mode, which spins down during light loads for near-silent operation.

Who is this for? The H2 Flow and C850 SFX are ideal for builders who need high-end performance in a small package—whether for a home office, a living room setup, or a portable gaming rig. The case’s airflow optimizations make it a standout for liquid-cooled builds, while the PSU’s modularity and efficiency appeal to those who prioritize clean cable management and energy savings. The limited-time H2 Mini PC offers an even more accessible entry point, though availability is restricted to the US market.
Tradeoffs? The vertical orientation may not suit every builder’s preference, and the prebuilt Mini PC lacks customization. However, for those willing to embrace a compact, high-performance approach, these components deliver a compelling blend of innovation and practicality. Availability for both the H2 Flow and C850 SFX begins immediately, with the H2 Mini PC launching as a special offer ahead of broader prebuilt releases.
