Product details

The cases of the Eclipse P400 Air series are aimed at beginners and also offer many interesting features for experienced PC enthusiasts, such as optimized airflow compared to its predecessor. The front of the Eclipse P400 Air is made of a metal plate with a fine mesh grid, which not only allows for excellent airflow but also keeps the interior of the case dust-free. The advantage of this solution compared to the previously common combination of mesh and dust filter is clear: air can be drawn in much more freely by the fans installed behind it. Additionally, the sturdy mesh also looks impressive, especially when the interior of the case is illuminated and shines through. Another visual highlight is the three pre-installed RGB LED fans, whose lighting is connected to an integrated controller and can be controlled via two switches on the I/O panel. Alternatively, the lighting can also be adjusted through compatible motherboards, such as those from ASUS, ASRock, Gigabyte, MSI, or via Razer's Chroma software. Another highlight is the modern side window made of tempered and tinted real glass, which provides a stunning view of the installed hardware and gives the case a particularly elegant appearance.

The Phanteks Eclipse G360A is a sensible successor to the P360A. It knows how to convince with a high compatibility for air and water cooling systems as well as good cooling. However, the overall result is somewhat marred by the design of the cable management system.

This test report belongs to a different type: Eclipse G360A (E-ATX, ATX, mATX, Mini-ITX)
