The Phanteks G400A is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most impactful advantage is the inclusion of fans, which represents a 100% improvement over the Fractal Design North. While both cases share an equal standing in half of the measured fields, the superior cooling hardware configuration gives the Phanteks G400A a clear edge in out-of-the-box functionality.

Users who prioritize immediate cooling performance and value the convenience of pre-installed hardware should choose the Phanteks G400A. Conversely, the Fractal Design North remains a viable option for builders who do not require the additional fans provided by the competitor. By focusing on these specific hardware differences, you can select the chassis that best aligns with your cooling requirements and assembly preferences.
