Product Description

Phanteks Eclipse P400 Air Midi Tower DRGB Case - White

The cases of the Eclipse P400 Air series are designed with beginners in mind while still catering for the experienced PC enthusiast crowd with an array of interesting features including, despite its sleek profile, optimised airflow. The front of the Eclipse P400 Air consists of a metal plate with a fine mesh grid which allows excellent airflow on one hand, while also allowing users to keep the interior of the case free of dust. When compared to the usual combination of mesh and dust filters, the advantage here lies in the fact that the fans situated behind the front panel are able to pull in air more easily. This durable mesh also happens to add a certain something to the overall look of the case - especially when the interior of the case is illuminated with RGB lighting.

An additional visual highlight of the case includes the three pre-installed RGB-LED fans, the lighting of which is controlled via an integrated controller and two switches located on the I/O panel. Alternatively, the lighting can be adjusted using a compatible motherboard, either from ASUS, ASRock, Gigabyte, MSI or using Razer's Chroma software. Users will also be pleased to note the inclusion of the tinted- as well as tempered glass side window, allowing for a panoramic view of their hard-earned gaming hardware and elevating the look of the case as a whole.

The PHANTEKS Eclipse P400 Air Midi-Tower from PHANTEKS' series of cases offers clean lines and an ascetic style in white and black. The metal mesh grid at the front in combination with the large tinted tempered glass side window all combine to give the case a high-end look, which is then emphasised with the LED lighting of the three pre-installed 120 mm fans at the front.

Users will find a convenient reset switch and both LED controllers located in the indentation between the roof and the upper air inlet in the front. In the centre of the case towards the front users will find a power button that even offers a backlit RGB-LED, while audio jacks and USB 3.0 ports on the front panel are also included. A large, removable dust filter, which acts like a large mesh grille and rests on a large vent takes up the majority of the lid.


The interior of the Eclipse P400 Air continues on with the premium looks of its exterior with attractive black paint. The inside of the case is divided in two by means of a PSU shroud complete with integrated air vents on its top. The presence of this PSU shroud helps conceal both drive bays, which in turn allow for tool-free mounting of two 3,5- or 2,5" drives via the case's right side after removing the side cover which is attached with user-friendly thumb screws. Up to two SSDs can be installed to the rear of the motherboard with "Drop-N-Lock" SSD brackets, and PHANTEKS also factored in convenient cable management - reserving 25 mm of space here for said purpose. Velcro cable ties enable users to neatly route their cabling and the presence of rubberised pass-throughs help to keep said cables in top condition.

The PHANTEKS Eclipse P400 Air has got hard core gamers covered when it comes to hardware: graphics cards up to 420 mm in length are supported with radiator mounts for AiO and custom water cooling solutions. The rear of the case also supports the installation of a 120 mm fan or a similarly-sized radiator if you prefer, while the front supports three 120 mm fans or two 140 mm fans. Instead of fans, if you prefer, the case will also support 280- or 360 mm radiators in the front. If users wish to install a 360 mm radiator however, a panel in the PSU shroud as well as the HDD cage must be removed. In addition to the three pre-installed 120 mm fans on the front, either two 120- or 140 mm case fans can be installed in the roof and a 120 mm fan mounted at the back.


Those wishing to add a larger traditional-style CPU cooler to their setup can opt for models up to 16 cm in height, while your gaming system is free to use power supplies up to 270 mm in length. The LED lighting of the fans can be connected to the case's integrated LED controller. The two switches at the front allow users to select from several lighting modes and colours. Alternatively, the lighting can be controlled via motherboard using a compatible RGB connector. The lighting can be controlled using ASRock Polychrome Sync, Gigabyte RGB Fusion, ASUS Aura or MSI Mystic Light Sync and even Razer's Chroma software, meaning that the motherboard's lighting can be coordinated in conjunction with the case's lighting - meaning your whole gaming PC can benefit from your exact choice of lighting and LED effects.

With the help of the accessories (available separately), users can forfeit the additional space for the GPU or radiator in the front and opt instead for up to four additional 3,5-/2,5" drives. There's even the possibility of installing the graphics card in a vertical orientation.
