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.

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.
