Product information

Description

Cooler Master MasterFrame 400 Mesh Black is a micro-ATX computer case designed to combine compact dimensions, effective airflow and a clear view of internal components. The case includes a transparent side panel and one preinstalled 120mm ARGB fan, and features a front mesh panel to support intake airflow. It is intended for mATX motherboards and smaller builds where space efficiency and thermal performance are required.

Advantages

The MasterFrame 400 Mesh offers a balance of ventilation and component visibility: the front mesh improves airflow to intake cooling components while the transparent side panel provides an unobstructed view of the interior. The included 120mm ARGB fan provides basic lighting and airflow out of the box, reducing the need for immediate accessory purchases. Its compact mATX form factor allows installation in smaller setups without compromising on standard desktop hardware compatibility.

Suitable for

  • Compact gaming PCs using micro-ATX motherboards
  • Home or office workstations requiring a small footprint
  • Builds where visibility of components (RGB lighting, cable management) is desired
  • Systems that benefit from improved front intake airflow

When it may not be suitable

Because this is an mATX case with a compact internal layout, it may not be suitable for full-size ATX motherboards or builds requiring many large expansion cards. High-end cooling configurations such as multiple large radiators or very long GPU + extensive storage arrays may be limited by available internal space and mounting locations.

Key specifications

  • Form factor: micro-ATX compatible
  • Side panel: transparent windowed panel
  • Preinstalled cooling: 1 × 120mm ARGB fan
  • Front panel: mesh design for intake airflow
  • Drive bays and expansion: accommodates typical mATX expansion slots and 2.5/3.5" drives depending on internal configuration
  • Front I/O and accessibility: standard top/front I/O layout for small cases (power, USB, audio) — check actual panel configuration before purchase

How to use

Install a micro-ATX motherboard and standard-length power supply following the case manual and manufacturer mounting points. Route cabling through the provided openings and secure drives in available 2.5" or 3.5" bays. Use the front mesh area for intake fans and position the included 120mm ARGB fan according to the case’s recommended airflow direction. If additional cooling or lighting is required, compatible ARGB headers on the motherboard can be used to synchronize lighting effects.

What to consider before purchase

  • Confirm motherboard form factor is micro-ATX or smaller
  • Check GPU length and CPU cooler height against the case’s internal clearance
  • Verify the number and types of drive bays you need (2.5" vs 3.5")
  • Ensure your power supply length fits the compact chassis

Usage recommendations

For balanced cooling, use the front mesh for at least one intake fan (in addition to the included 120mm ARGB) and ensure unobstructed airflow paths. Keep cabling tidy to maintain airflow and consider adding one exhaust fan at the rear or top if thermals require it. Match ARGB connections to a compatible header or controller to manage lighting effects.
