NZXT H3 Flow vs Fractal Design Node 804 - Black - Compact Computer Case - mATX - High Airflow -

Design and Build Quality

The NZXT H3 Flow and the Fractal Design Node 804 both focus on compact micro-ATX builds but take different design approaches. The H3 Flow emphasises a space-saving chassis with a high-airflow design, utilising ultra-fine steel mesh panels to maximise ventilation while filtering dust. Conversely, the Node 804 features a dual chamber layout with an elegant brushed aluminium front panel, reflecting a Scandinavian minimalist aesthetic.

While the H3 Flow prioritises airflow with mesh in its design, the Node 804’s dual chamber case layout separates components for better cooling efficiency. The Node 804 also offers a more premium exterior finish with aluminium, compared to the steel mesh on the H3 Flow. Both cases cater to users wanting compactness; however, the Node 804’s design leans more towards a sophisticated look, whereas the H3 Flow is purely utilitarian with a focus on airflow.

Cooling and Airflow

Cooling capabilities strongly favour the Fractal Design Node 804 due to its dual chamber layout and included fans. The Node 804 comes with three Fractal Design Silent Series R2 fans pre-installed and space for up to seven additional fans, supporting up to four radiators simultaneously. This makes it highly adaptable for custom water cooling setups and robust air cooling.

The NZXT H3 Flow supports up to seven fans as well, with a pre-installed rear F120Q (CV) fan, and radiator support includes up to a 280 mm unit at the front and 240 mm at the top. Its ultra-fine mesh panels also contribute to airflow and dust filtering. While both cases provide extensive cooling support, the Node 804’s three included fans and the ability to mount four radiators simultaneously give it a clear advantage for users seeking superior cooling flexibility.

Internal Space and Compatibility

In terms of component compatibility, the NZXT H3 Flow supports full-size graphics cards up to 377 mm without front fans, 352 mm with front fans, and 317 mm with front radiator and fans installed. This flexibility allows for high-performance GPUs in a compact chassis. The Fractal Design Node 804 focuses on storage and cooling, with a unique hard drive mounting system capable of housing up to 8 x 3.5” and 4 x 2.5” drives or alternatively up to 10 x 3.5” and 2 x 2.5” drives.

While the H3 Flow’s strength lies in GPU clearance and accommodating high-performance components, the Node 804 excels in storage capacity and multi-drive configurations. Both cases support micro-ATX motherboards, but the Node 804’s dual chamber layout and extensive drive mounting options make it well suited for users needing significant storage alongside robust cooling.

Storage Capacity

Storage options present a significant difference between the two cases. The Node 804’s hard drive mounting system is notable for its capacity, fitting up to 8 x 3.5” and 4 x 2.5” drives, or an alternative configuration of 10 x 3.5” and 2 x 2.5” HDD/SSD drives. This makes the Node 804 an excellent choice for enthusiasts or professionals requiring large-scale local storage.

In contrast, the NZXT H3 Flow does not specify any particular storage mounting system or capacity. Its design prioritises airflow and GPU size rather than storage expansion. Therefore, users needing extensive drive bays and storage flexibility will find the Node 804 far superior in this regard.

Water Cooling Support

Both cases provide water cooling readiness, but the Node 804 offers more extensive options. It supports up to four radiators simultaneously, allowing complex custom liquid cooling loops. The three included Silent Series R2 fans also help to maintain quiet yet efficient airflow in these setups.

The H3 Flow supports a 280 mm radiator at the front and a 240 mm radiator at the top, covering most common AIO liquid cooling configurations. However, it does not match the Node 804’s potential for multiple radiators at once. Users prioritising multi-radiator water cooling systems are better served by the Node 804’s design.

Price and Value

The NZXT H3 Flow is priced at £51.99, making it a budget-friendly option for micro-ATX builds focused on airflow and GPU size. The Fractal Design Node 804 costs significantly more at £117.43, reflecting its premium materials, multi-drive capacity, and extensive cooling features.

The H3 Flow offers excellent value for users seeking a compact, high-airflow case without extensive storage or multi-radiator needs. The Node 804’s higher price is justified by its advanced dual chamber design, included fans, and superior storage and cooling support, targeting enthusiasts who require these features.

Which should you buy?

Choosing between the NZXT H3 Flow and the Fractal Design Node 804 depends on your priorities. For a compact, affordable micro-ATX case with strong GPU support and high airflow through mesh panels, the H3 Flow at £51.99 is an excellent choice. It suits users who want a straightforward build focused on performance and dust filtering without extensive storage or complex cooling setups.

On the other hand, if you need a case that supports large storage arrays, multiple radiators, and comes with three quiet fans included, the Node 804 at £117.43 is clearly the superior option. Its dual chamber layout and premium aluminium finish offer better cooling efficiency and aesthetics, making it ideal for enthusiasts or professionals who require maximum flexibility and storage capacity.

Ultimately, the H3 Flow offers great value for airflow and GPU clearance, while the Node 804 excels in cooling versatility and storage, justifying its higher price for those needs.
