Mesh front panel for maximum airflow

Mesh front panel for maximum airflow

The micro-perforated metal mesh panel increases airflow to the front fans and helps maintain stable temperatures even while gaming. At the same time, it reduces dust intake into the case interior.

3× ARGB fans with FDB included

Included are 3× 120mm ARGB fans with FDB bearings (2× front + 1× rear) for efficient cooling, lower noise, and long lifespan. The case supports up to 7× 120mm fans and a 240mm radiator at the top.

Tempered glass and separate PSU chamber

Tempered glass and separate PSU chamber

The tempered glass side panel highlights your components and lighting, while the bottom PSU chamber hides the power supply and cabling. The result is a cleaner-looking build and improved airflow around the graphics card.

MC-ONYX is a high-performance microATX case designed for maximum airflow in compact dimensions. The micro-perforated metal mesh brings cool air directly to the front fans and helps keep temperatures under control even in demanding gaming builds. The tempered glass side window also showcases components and lighting beautifully.

Cooling without compromise: the case comes pre-installed with 3× 120mm ARGB fans with FDB bearings (2 front + 1 rear) to combine high airflow, lower noise, and long lifespan. It supports up to 7× 120mm fans and a top-mounted radiator up to 240 mm, so you can choose either air or liquid cooling.

Practical internal layout with a separate bottom PSU chamber improves airflow in the graphics card area and helps hide cables for a cleaner build. Front-panel connectivity is within easy reach for everyday use.
