The Phanteks Eclipse P400A breathes performance with its full metal mesh front panel. Thanks to engineering improvements we have been able to create an Ultra-Fine Performance Mesh that brings the best possible performance while keeping dust from entering the system.

Strength & Performance

Full-Metal Mesh Front Panel

The single-piece front panel is made from an Ultra-Fine Steel Mesh. This mesh catches dust, adds structure and strength, and is part of the P400A's seamless design.

Improved Airflow

The P400A chassis has improved airflow to keep your system cool. The optimised High Air-flow Mesh Front Design offers maximum cooling performance.

Integrated Digital-RGB Lighting and Expansion

The integrated Digital-RGB lighting can be easily controlled with the Mode and Colour buttons. The Digital-RGB Controller can also be expanded and synced to a compatible motherboard.

Cooling Capacity

The Eclipse P400A has a range of possible fan and radiator locations up to 360mm for both 120mm and 140mm fans.

Storage Capacity

The P400A supports 3 x 3.5" HDDs and 2 x 2.5" SSDs out of the box with easy to use trays and vibration dampening. There is space for an additional four drives with the optional PH-HDDKT_02 brackets.

It does not look like there would be enough room, or it would be too close to try. -MR

Q: does it come with a fan splitter and a rgb splitter
Answer by Matthew on 7th October 2019
It comes with an integrated controller that supports the fans and their RGB settings.

Answer by Website User on 27th December 2019
This case hasn't got any splitter. You connect your fans in daisy chain. Fans have three connectors. One is RGB, with another connector to pass through to another fan, and another is 3 pin to your motherboard. Please note, they are not PWM controlled fan, but voltage contolled fans. Motherboard should support both, so thats not an issue.

One of the best gaming cases around the market. Great airflow through the case, so the overall temperature inside stays lower.

This is the first case I bought in several years, and I have to say it was a huge upgrade. My temps are a lot lower, and the front 3 fans look very nice. There's a lot of space inside the case, so it was very easy to install everything, definitely recommend this, especially so at the price range.
