SilverStone ALTA G1M

This innovative Micro-ATX tower redefines compact performance with its unique stack effect design and ultra-small footprint.

Engineered for both aesthetics and airflow, it features a 90-degree rotated motherboard layout and a mandatory cable routing system that keeps all sides clean and cable-free.

Despite its minimal size, it supports high-end components — including graphics cards up to 355mm and 360mm radiators for advanced liquid cooling setups.

At the heart of its thermal design is a powerful 180mm Air Penetrator fan, optimizing vertical airflow to enhance the natural stack effect and ensure efficient heat dissipation.

Distinctive SilverStone design recognized by the masses

Embodying the characteristics & qualities of the iconic Fortress FT03,

ALTA G1M features a 90-degree rotated motherboard layout and a small overall footprint that’s tall in height but short on depth.

Hot air rises, and rising air cools

By following the natural convection of air, ALTA G1M’s layout design combined with a pre-installed Air Penetrator 180mm fan,

contributes to excellent bottom-to-top directional airflow (stack effect), which takes advantage of hot air’s natural tendency to rise.

Built for the highest-end of today’s components

ALTA G1M is compatible with a maximum of a 360mm radiator

whilst capable of accommodating graphics cards of any length, and of any height up to 4 slots.
