SilverStone ALTA G1M Micro-ATX Case — Stack Effect Cooling with 90-degree Rotated Layout

A recognizably SilverStone silhouette inspired by the iconic Fortress FT03, the ALTA G1M brings that signature aesthetic to a Micro-ATX tower. Its 90-degree rotated motherboard layout and compact footprint make the chassis tall in stature while keeping depth to a minimum. The case leverages natural convection (stack effect) for cooling: hot air is guided upward by the internal layout and a pre-installed Air Penetrator 180 mm fan, producing strong bottom-to-top directional airflow. Designed for high-end builds, the ALTA G1M supports a maximum 360 mm radiator and can house graphics cards of any length and of any height up to 4 slots.
