Thermal efficiency and compact size
Designed for enthusiasts looking to combine compactness and performance, the NZXT H3 Flow case is the perfect example of intelligent, optimised design. Despite its reduced dimensions, it offers extensive compatibility with high-end components, including full-size graphics cards and advanced cooling systems. Thanks to its ultra-fine mesh panels and ventilated PSU cover, it ensures constant airflow while effectively trapping dust. Its pre-installed rear fan further enhances thermal efficiency right out of the box, and it focuses on ease of use without compromising customisation options. It is compatible with motherboards with rear connectors for a finish without visible cables, and offers tool-free access to all panels, simplifying maintenance and modifications. Its integrated cable management allows for tidy organisation, while its ability to accommodate up to seven fans and multiple radiators means you can configure a bespoke cooling system, even in a tight space.
Key features:
- Compact micro-ATX format compatible with high-performance components
- Ultra-fine mesh panels for optimised airflow and efficient filtration
- Accommodates GPUs up to 377 mm depending on configuration
- Supports up to 7 fans and heatsinks up to 280 mm
- F120Q rear fan (CV) included for immediate cooling
- Integrated cable management with channels and attachment points
- Compatible with rear-connect motherboards (ASUS BTF, MSI Project Zero)
- Tool-free access to panels for simplified maintenance
