Phanteks Eclipse P400S Case Overview
The Eclipse P400S is a mid tower case and has the official dimensions of 210 mm x 465 mm x 470 mm (W x H x D). We received the black version of the case, but it also comes in white as well as gunmetal.
At the front of the case we have no drive bays at all, this is something many case manufacturers are moving to. Not many people I know even use optical media these days. There are vents at the top and bottom of the case that allow air to flow into the front of the case.
The front of the case easily pops off is you pull it from the bottom. Once removed we can see that it features a large piece of sound-dampening material. Installed in the front of the case is a 120 mm intake fan. There is room in the front for three 120 mm fans or two 140 mm fans. That means you will have room for water cooling radiators up to 360 mm. At the bottom of the case there is a LED strip. This is an RGB strip and it is compatible with RGB control modules and RGB headers like you will find on ASUS motherboards.
At the top of the case you will find all of your controls and connections. At the center you have a very large power button. To the right are two USB 3.0 ports and HD audio connections. Hidden are three more buttons, they are under the top edge of the case. They are labeled on the top of the case. They include the speed control for the included fan controller, LED color switch button for the LED strip and LEDs around the power button, and a reset button.
Moving towards the back of the case we have two sound dampening plates. These are held on to the top of the case by magnets. It is great that this is not just one big plate because if you only want to install one fan up here you still get some sound dampening qualities. Once removed you can see that we have a large ventilated section. You have room up here for two 120 mm or two 140 mm fans. If you are going to install cooling at the top of the case Phanteks includes two magnetic filters.
Since this is a silent case we do not have a window, although there are windowed versions of both the P400S and P400.
At the back of the case we have our second fan, which is a 120 mm exhaust fan. Phanteks uses the “slit” system so you have the ability to move the fan up and down if you wish. Below that we have seven expansion slots and our power supply mount is on the bottom of the case. You will also notice thumbscrews on both side panels for easy access into the case.
Flipping the case over to the bottom there are four rubber feet that will lift the case off of the ground for better airflow. There is also a removable fan filter that can be pulled out from the back of the case for easy cleaning and maintenance.
