SilverStone Technology ALTA G1M Micro-ATX Tower Case - Black, Tempered Glass, 90° Motherboard Rotation, 180mm Air Penetrator Fan

Rotated 90 degrees, the motherboard in the SilverStone ALTA G1M leverages natural convection for a 'stack effect' that efficiently exhausts heat. A bottom-mounted 180mm Air Penetrator fan pushes cool air upward, while the tempered glass side panel showcases your build in a sleek black chassis.

Overview

The ALTA G1M redefines small form factor cooling. By orienting the motherboard vertically, it creates a direct airflow path from bottom to top, efficiently exhausting heat. The included 180mm fan draws cool air from beneath the case, while top and rear fan mounts allow for additional airflow or liquid cooling radiators. With support for graphics cards up to 350mm and CPU coolers up to 175mm, it accommodates powerful hardware without compromise.
