Product Description

NZXT H3 Flow Micro ATX Clean White Airflow Champion

Streamlined Airflow for Maximum Cooling Efficiency

The NZXT H3 Flow Micro ATX case is purpose-built for high-performance airflow in a compact form. Designed with a mesh front panel and open interior layout, this case ensures excellent ventilation, making it ideal for gaming builds and performance PCs that demand cool and quiet operation. Whether you're running high-end components or just want reliable thermal management, the H3 Flow is optimized to maintain lower temperatures without compromising on aesthetics.

Compact Size with Serious Compatibility

Despite its smaller footprint, the H3 Flow supports Micro-ATX and Mini-ITX motherboards, large graphics cards, and full-sized power supplies. It provides ample clearance for CPU coolers and radiators, giving you the flexibility to build a system tailored to your performance needs. Cable management is clean and efficient thanks to its smart internal layout, ensuring your build looks sharp and runs smoothly even in tight spaces.

Modern Design with a Minimalist Aesthetic

Finished in a sleek all-white design, the NZXT H3 Flow adds a modern, minimalistic touch to any setup. The steel frame construction and tempered glass side panel highlight your components while maintaining structural integrity. With a clean front I/O panel, including USB 3.2 and audio ports, the H3 Flow combines functionality with style, making it the perfect foundation for your next Micro ATX build.
