    The GAMDIAS ATLAS M3M is a Micro-ATX/Mini-ITX PC case with three-sided tempered glass, three built-in ARGB fans, and angled airflow; it suits compact gaming builds that need room for a graphics card up to 400 mm and a clear view of the components.

    Recommended For

    • Builders creating a compact Micro-ATX or Mini-ITX desk PC who want the motherboard, GPU, and lighting visible through glass on three sides.
    • Gaming-PC builders who want a showcase case for a long graphics card; the angled airflow design and GPU clearance up to 400 mm are aimed at this kind of build.
    • PC builders who want ARGB lighting and fan control included, rather than starting with an empty case: it comes with three ARGB fans and an 8-port PWM/ARGB hub.
    • Builders planning a connector-hidden motherboard who want a cleaner-looking display build with less visible cabling.
