PC Case Cooler Master Cosmos C700M Full Tower Black, Grey, Silver

The Cooler Master Cosmos C700M Full Tower in Black, Grey and Silver is a high-capacity PC case engineered for flexible system layouts, advanced cooling options and visible component presentation. With a full tower form factor it supports Mini-ITX, Micro ATX, ATX and EATX motherboards and accommodates multiple storage drives and large cooling solutions. The chassis ships with three pre-installed 140mm front fans, a panoramic curved tempered glass side panel and brushed aluminum panels with cast aluminum handles and feet for sturdy handling.

Advantages

The Cosmos C700M offers a highly versatile internal frame that supports conventional, chimney, inverse or fully custom layouts, enabling a wide range of component positioning and bracket configurations. A dedicated graphics card bracket supports both vertical and horizontal mounting and includes a 400mm riser cable for vertical GPU installations. The case includes addressable RGB lighting strips that run from the top to the front panel and ambient ARGB lighting at the bottom. Extensive cable covers and modular mounting (M. Port) allow neat cable management and additional mounting of SSDs or reservoirs. Two flat radiator brackets each support up to 420mm radiators for flexible liquid cooling placement on the top, front or bottom.

Suitable for

• High-end gaming builds with large GPUs and multiple cooling loops
• Workstations requiring EATX motherboard compatibility and extensive storage
• Custom liquid-cooling projects with large radiators and dual-bracket support
• Showcase systems using tempered glass side panels and ARGB lighting

How to use

Install the motherboard in the appropriate standoffs for Mini-ITX, Micro ATX, ATX or EATX and route power and data cables using the included cable covers and modular M. Port attachments to maintain clean airflow. Mount storage devices into the 2.5" or 3.5" bays or the 5.25" bay as required, and attach the PSU (not included) in the designated location. Use the graphics card bracket to mount GPUs vertically or horizontally and connect vertically mounted cards with the supplied 400mm riser cable. Position radiators and fans using the flat radiator brackets on the top, front or bottom depending on your cooling layout and space requirements.

Recommendations

For optimal airflow and cooling performance, combine the pre-installed front 140mm fans with additional intake or exhaust fans in the top or rear positions, and plan radiator placement to avoid obstructions from drive cages. Use the cable covers and M. Port mounting options to separate power cables and fluid tubing where possible. When mounting GPUs vertically, ensure the riser cable is securely connected and that clearance is sufficient for cooler shrouds and radiator placement.
