Caixa de computador Cooler Master MasterFrame 400 Mesh prateado, mATX, painel lateral transparente, 1x ventoinha ARGB de 120 mm

The Cooler Master MasterFrame 400 Mesh Silver is a mid-tower computer case designed for micro-ATX (mATX) builds. It features a mesh front panel for improved airflow, a transparent side panel to display internal components, and one preinstalled 120 mm ARGB fan for basic illumination and airflow. The case supports compact gaming systems or small workstations where cooling efficiency and component visibility are priorities.

Advantages

The mesh front enhances intake airflow, helping to maintain lower temperatures for CPU and GPU components in confined mATX layouts. The transparent side panel provides clear visibility of installed hardware and cable routing, suited for users who value neat interior presentation or want to showcase RGB lighting. Integrated ARGB lighting on the preinstalled fan offers immediate visual customization and is compatible with common motherboard ARGB headers for synchronized effects.

Suitable for

• Compact gaming builds based on mATX motherboards
• Small home or office workstations requiring efficient airflow
• Users who want a visible interior for component display or RGB setups
• Enthusiasts seeking a balance between cooling and a compact chassis footprint

When it may not be suitable

This case may not be suitable for full-size ATX builds or systems requiring multiple large GPUs due to its mATX-oriented internal space. Users who plan extensive liquid cooling radiators, numerous 3.5" drives, or very large tower CPU coolers should verify component dimensions against the case’s clearance specifications before purchase.

Key specifications

• Form factor: Mid-tower design for micro-ATX motherboards
• Side panel: Transparent panel for internal component visibility
• Front panel: Mesh design for improved airflow
• Preinstalled cooling: 1 × 120 mm ARGB fan included
• Supported cooling: Multiple fan mounting points and radiator support in compact layout (verify specific clearance for larger radiators)
• Drive bays: Support for standard 2.5" and 3.5" drive configurations (check exact mounting count)
• Expansion: Slots and internal space sized for mATX expansion cards

How to use

Install an mATX motherboard using the included standoffs and secure the power supply in the designated compartment. Mount storage drives into the appropriate 2.5" or 3.5" trays and connect power and data cables. Use the mesh front and available fan mounts to configure additional cooling as needed; connect the preinstalled 120 mm ARGB fan to a compatible ARGB header on the motherboard to control lighting effects. Route cables behind the motherboard tray where possible to maintain unobstructed airflow and a tidy interior view through the transparent side panel.

What to consider before purchase

• Confirm motherboard size: designed for micro-ATX form factor
• Check CPU cooler and GPU clearance against case dimensions
• Verify the number and type of drives you plan to install
• Ensure your motherboard supports ARGB headers if synchronized lighting is required

Recommendations

For balanced airflow, install intake fans behind the mesh front and position exhaust fans at the rear or top. Use 2.5" SSDs for compact storage needs and route power cables through the back to maximize unobstructed airflow and showcase a clean interior behind the transparent side panel.
