Product information

Description

The Cooler Master Cosmos ALPHA Full Tower PC Case Black and Silver with Side Window, ATX Motherboard Support, Cable Management, and Liquid Cooling Capability is a spacious and robust full tower computer case built to house high-performance gaming systems and advanced workstation builds. Combining a striking black and silver metal exterior with a functional side window, this chassis offers a clear view of internal components while maintaining structural integrity. Designed with extensive interior volume and thoughtful layout options, it accommodates large hardware components efficiently while providing advanced airflow and liquid cooling support to keep demanding systems operating at optimal temperatures.

Advantages

This full tower PC case provides exceptional internal space with a total volume of 140 liters, making component installation straightforward and accommodating large hardware configurations easily. The robust metal construction ensures long-lasting durability and secure housing for heavy components. Advanced cooling flexibility is a primary benefit, featuring pre-installed front and rear fans along with extensive support for top, bottom, and side radiators and fans. Integrated anti-dust filters help maintain internal cleanliness by reducing dust buildup over time. Furthermore, the chassis incorporates comprehensive cable management routing options to keep internal wiring tidy and promote unobstructed airflow, complemented by easily accessible front-panel USB Type-C and Type-A ports.

Suitable for

  • High-performance gaming PC builds
  • Advanced liquid-cooled computer systems
  • Workstations requiring ATX motherboards
  • Setups using large graphics cards up to 40 cm in length

When it may not be suitable

This chassis may not be suitable for compact or portable desktop setups due to its large Full Tower form factor, substantial physical dimensions, and heavy weight of 27.5 kg. Users looking for a minimalist, lightweight, or space-saving micro-ATX or mini-ITX enclosure might find this enclosure overly large for their needs.

Key specifications

  • Form factor: Full Tower PC case
  • Motherboard support: ATX
  • Maximum graphics card length: 40 cm
  • Maximum CPU cooler height: 18.6 cm
  • Maximum power supply length: 24 cm
  • Material: Metal
  • Side window: Yes
  • Expansion slots: 8
  • Internal 3.5" drive bays: 2
  • Cooling support: Front pre-installed 200 mm fans, rear pre-installed 120 mm fan, top radiator support up to 360 mm
  • Front ports: USB Type-C ports, USB Type-A ports, audio input and output
  • Dimensions: 669 mm width, 330 mm depth, 639 mm height
  • Weight: 27.5 kg

How to use

Begin the installation process by removing the side panels to access the interior chamber. Mount your power supply at the bottom of the case, ensuring it matches the supported ATX form factor up to 24 cm in length. Install your ATX motherboard into the main compartment, securing it to the standoffs provided. Next, mount your CPU cooler, keeping within the 18.6 cm height limitation, and install your graphics card, ensuring it does not exceed the 40 cm length limit. Connect necessary cables using the internal cable management routes to maintain a clean layout. Secure your storage drives in the available 3.5" bays or combo cages. Finally, configure your cooling setup by utilizing the pre-installed fans or mounting additional liquid cooling radiators and fans as required before closing the side window panel.

What to consider before purchase

  • Verify that your desk space and room layout can accommodate a large and heavy chassis measuring 669 x 330 x 639 mm and weighing 27.5 kg.
  • Check that your chosen components, such as the CPU cooler height and graphics card length, align with the case limitations.
  • Ensure your power supply unit conforms to the ATX form factor and does not exceed 24 cm.
  • Confirm your motherboard dimensions match the supported ATX standard.
Usage recommendations: To maintain optimal thermal performance and component longevity, regularly clean the integrated anti-dust filters and ensure the surrounding area of the case remains unobstructed for proper intake and exhaust airflow.
