SilverStone Releases New ALTA Series Micro-ATX Gaming Chassis – ALTA G1M

ALTA G1M is the second installment of the flagship ALTA series chassis line, that embodies the characteristics & qualities of the iconic Fortress FT03, while delivering extraordinary building experience for today’s highest end hardware components.

The exterior of ALTA G1M stands out immediately with its classic 90-degree rotated motherboard layout inherited from the Fortress FT03, which dramatically reduces chassis’ overall footprint as it is tall in height and short on depth. Equipped with 1 x 180mm Air Penetrator intake fan, this layout contributes to the excellent bottom-to-top directional airflow (stack effect) design, which takes advantage of hot air’s natural tendency to rise, while also maintaining a streamlined look with no visible cabling on all four sides of the chassis.

ALTA G1M provides users with excellent usability & upgradability with its modular design that allows removal of all 4 panels and the cover on top.

Beside the stack effect design, hardware compatibility is greatly improved to support the latest components. ALTA G1M can accommodate graphics cards of any lengths, thickness, and height, with support for SFX-L PSU of up to 130mm and CPU cooler height of up to 159mm. The included bracket supports radiators of up to 360mm, 3 x 120mm fans or 2 x 2.5"/3.5" drives.

The exterior of the chassis has plenty of ventilation holes to keep power hungry components breathing with fresh air. Front I/O includes a standard 3.5mm combo audio jack, 2 x USB 3.0 and 1 x USB Type-C port positioned on the bottom right-front for convenient access.
