The cases of the Eclipse-P400-Air series are aimed at beginners and also offer many interesting features for experienced PC enthusiasts, such as the optimized airflow compared to its predecessor. This is because the front of the Eclipse P400 Air is made of a metal plate with a fine-mesh grille, which on the one hand enables excellent airflow and on the other keeps the inside of the case free of dust. The advantage of this solution compared to the previously common combination of mesh and dust filter is obvious: the air can be drawn in much more freely by the fans installed behind it. In addition, the stable mesh also looks good, especially when the case is illuminated and shines through. Another optical highlight are 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 via compatible motherboards, for example from ASUS, ASRock, Gigabyte, MSI or via the Chroma software from Razer. A further highlight is the modern side window made of tempered and tinted real glass, which provides a breathtaking view of the installed hardware and gives the case a particularly elegant appearance.
