The Cosmos

The debut of the COSMOS C700P in 2017 set new standards in modularity, further pushing the limits of PC building and paving the way for the latest release of the COSMOS C700M.

Created to challenge the stereotypical layout of conventional PC cases, the COSMOS C700M further adapts the COSMOS framework to encourage layout experimentation. Taking modularity a step further while having features that stay true to the COSMOS legacy, the COSMOS C700M boasts two curves on the tempered glass side panel and features the series’ iconic aluminum handles.

Raising the bar(s)

The freedom in layout organization and the support for unique graphics card mounting make custom building accessible as soon as the COSMOS C700M is unboxed. The idea is to inspire growth in builders across all levels—since the chassis is only as complex as builders need it to be, there will always be room to creatively experiment. If modders decide to take customization even further, the COSMOS frame allows for sandbox-level versatility. The COSMOS C700M keeps Raising the Bar(s) on custom PC’s by inspiring builders to escape from the “standard” layout.

ARGB Lighting

Two parallel strips of addressable RGB lighting run continuously from the top panel to the front panel, with ambient ARGB lighting on the bottom that reflects against the aluminum bars.


The graphics card bracket can be mounted vertically or horizontally on either the PSU midplate or on the M. Port. The bracket can also be rotated from 0 to 90 degrees. Also included is a 400mm riser cable for the convenience of being able to connect a vertically mounted graphics card to the motherboard.


The 3 included covers can be placed on either the M. Port or on the mid-plate, with the ability to mount SSD storage or a reservoir.


Brushed aluminum spans the top panel and front panel, with cast aluminum handles (and feet) that provide protection & support for carrying the case.


A flat radiator bracket design offers more versatility for liquid cooling with the ability to be mounted on the top, front, or bottom of the frame. The two included brackets can each support a 420mm radiator, with the ability to mount fans and a radiator on either side of the bracket.


The advanced I/O panel comes with a 4-Pole headset jack (audio+mic), USB 3.1 (Gen 2) Type-C port, four additional USB 3.0 ports, PWM fan speed button, and an addressable RGB control button.


A panoramic tempered glass side panel, with two curved edges, offer a wide view of the system build.
