Cooler Master MasterBox MB400L Mini Tower Case

The Cooler Master MasterBox MB400L is a mini tower chassis built for Micro-ATX motherboards. It ships in a black finish and includes support for an optical disc drive. The case is sold in new condition and arrives fully functional.

Builders needing Micro-ATX flexibility

This case suits builders who want a compact Micro-ATX layout and still need a 5.25 inch bay for an optical drive. It is not for users who require full ATX or E-ATX motherboard support. It is also not for builds that demand extensive liquid cooling radiator space or high airflow mesh front panels.

Micro-ATX form factor support decides fit

The single specification that determines compatibility is the Micro-ATX form factor support. Only motherboards matching this standard will mount correctly inside the chassis. Verify your board matches this form factor before purchase.

Highlights

  • Micro-ATX form factor fits compact builds
  • Mini-tower chassis saves desk space

Questions about this item

Does this Mini Tower case include a drive bay for an optical drive?

Yes, the supplier title confirms the MB400L ships with an ODD bay so you can install a DVD or Blu-ray drive.

Will a standard Micro-ATX motherboard fit without modification?

The case is built to the Micro-ATX form factor, so any board of that size mounts directly to the standoffs.

How can I verify the front-panel USB and audio connectors are working after assembly?

Plug in a USB device and headphones; if the device is recognised and audio plays, the internal headers are seated correctly.
