Phanteks P400 Eclipse Tempered Glass Chassis Review

A Closer Look – Interior

There are four aluminium thumb screws holding the side panel in place. With these removed, the panel simply lifts away, giving you lots of room to fit your hardware. The installation should be easy enough, as there’s a huge CPU cooler cut-out at the back, and cable routing holes and grommets where you’ll need them most.

Up top, a reasonable amount of room for mounting additional cooling.

There’s a ventilated PSU cover too, which should help keep things neat and tidy. Towards the front, you’ll also find pre-cut water cooling mounts.

In the back of the chassis, a pre-installed 120mm fan. You could easily swap this for a 120mm radiator too, if you desire.

In the front, a single 120mm fan is pre-installed. Of course, there’s a lot of space here for water cooling hardware, or additional fans.

Behind the motherboard, there’s a decent amount of room for cable routing. Of course, there are some cable tie loops and pre-installed straps to help keep things neat and tidy.

There are two dedicated 2.5″ drive mounts directly behind the motherboard.

You’ll also find two slide out tray mounts for 2 x 3.5″ or 2.5″ drives below the PSU cover. Of course, there’s also room for an ATX PSU, and plenty of spare space for excess cables too.
