NZXT has launched the H2 Flow, a mini ITX chassis available now for $150 (€138) that fits a full desktop GPU in just 20.7 liters of space. The case supports graphics cards up to 331 mm (13 inches) long, includes mesh side panels for airflow, and accommodates liquid cooling radiators up to 280 mm. Alongside the standalone case, NZXT is offering a limited pre-built H2 Mini PC configuration that slots a desktop NVIDIA GeForce RTX 5080 into that same compact enclosure.
The pre-built system comes in two processor configurations: one with an Intel Core Ultra 9 285K Arrow Lake chip and another with an AMD Ryzen 7 9800X3D. Both share the same core build: 32GB of DDR5-4800 memory across two Team T-Force Delta RGB 16GB sticks, a 2TB WD Blue SN5000 M.2 NVMe SSD, a Lian Li SP850G.B 850W SFX power supply, and a Kraken Elite 240 CPU cooler. A PCIe Gen 5.0 x16 riser cable and dual 120mm fans round out the internals.
Linux users considering either configuration will find the hardware well-supported. Both the Ryzen 7 9800X3D and Core Ultra 9 285K have been tested under Ubuntu and other distributions without issue, and NVIDIA's RTX 5080 (Blackwell architecture) is fully supported via NVIDIA's open-source GPU kernel modules, which are now mandatory for the 50 series and require driver version 570 or newer. Users have confirmed the open kernel modules working on distributions including Ubuntu, Arch Linux, and Debian 13.
The finished system measures 435 x 181 x 263 mm (17.1 x 7.1 x 10.4 inches), making it noticeably larger than typical mini PCs but considerably more compact than a standard desktop tower. The H2 Mini PC is priced at $3,500 (€3,220) and is currently listed as out of stock in both configurations. It is only available in the United States. Both the case and the pre-built system come with a two-year warranty.
