Micro-ATX Dual-Chamber Case

The ATLAS M3M is a dual-chamber micro-tower built for Micro-ATX and Mini-ITX motherboards. Three-sided columnless tempered glass panels give a full view of the interior. It also supports connector-hidden motherboards for a cleaner cable presentation.

Angled GPU Airflow and Fan Hub

A unique angled fan mounting system directs airflow straight toward the graphics card, supporting models up to 400 mm long. Three pre-installed NOTUS M1 ARGB fans include two reverse intake units, and an 8-port PWM ARGB hub handles lighting and speed synchronisation. Perforated vents on the side, front and rear complete the ventilation path.

For Compact Showcase Builds

This case suits builders who want a compact showcase with strong GPU cooling and simplified cable routing. It is not for anyone needing ATX or E-ATX motherboard support, multiple 3.5-inch drive bays, or a traditional single-chamber layout.

Questions about this item

How long a graphics card fits inside the ATLAS M3M?

The case accepts graphics cards up to 400 mm long, so most current dual-slot and triple-slot models will install without hitting the front panel or the angled fan brackets.

What noise and temperature levels should I expect when the three built-in NOTUS M1 ARGB fans run all day?

The three pre-installed NOTUS M1 ARGB fans connect to the included 8-port PWM ARGB hub, letting the motherboard regulate speed by temperature; under typical loads they run quietly, and the perforated side, front and rear vents let heat escape so internal temperatures stay stable during long sessions.

Which motherboards and front-panel connectors must I already have for this case to work?

You need a Micro-ATX or Mini-ITX board — standard or connector-hidden — plus an internal USB 3.2 Gen 2 Type-C header on that board to activate the front-panel Type-C port; the 8-port PWM ARGB hub also requires a 5 V ARGB header and a PWM fan header for full lighting and speed control.
