Product information

Description

The SilverStone ALTA G1M Mini Tower is a Micro-ATX PC case that uses a stack-effect layout with a 90-degree rotated motherboard to enable strong bottom-to-top airflow. The compact footprint (200 mm W x 307 mm D x 507 mm H) and tall profile make it suitable for space-saving builds while supporting high-end components including long graphics cards and up to a 360 mm radiator. The case includes a pre-installed 180 mm Air Penetrator fan, supports SFX and SFX-L power supplies, and provides mounting for both 3.5" and 2.5" drives.

Advantages

The rotated motherboard layout and stack-effect airflow leverage natural convection to move hot air upward, assisted by the pre-installed 180 mm Air Penetrator fan for efficient bottom-to-top ventilation. The ALTA G1M accepts a 360 mm radiator and graphics cards of any length and up to 4-slot height, offering compatibility for high-performance components in a compact Mini Tower form factor. Front I/O includes two USB 3.2 Gen 1 Type-A ports, and the steel/plastic construction balances durability with weight.

Suitable for

Compact gaming PCs that require long GPUs
High-performance small-form-factor workstations
Systems using SFX or SFX-L power supplies
Builds that prioritize natural convection and quiet airflow

Key specifications

Pre-installed fan: 1 x 180 mm Air Penetrator (bottom)

Power supply support: SFX, SFX-L
I/O: 2 x USB 3.2 Gen 1 Type-A
Material: Steel, Plastic; Colour: Black; Weight: 6 kg

How to use

Install an SFX or SFX-L power supply and mount the motherboard rotated 90 degrees according to the case's standoffs. Fit storage drives into the available 3.5" and 2.5" bays, then install the graphics card (up to 4-slot height) and any cooling components. If using liquid cooling, mount a radiator up to 360 mm where indicated by the case layout. Connect front-panel USB and power cables to the motherboard and ensure the pre-installed 180 mm fan is unobstructed to maintain the designed bottom-to-top airflow.

Usage recommendations

To maximize the stack-effect cooling, keep bottom intake and top exhaust areas clear of obstructions, use SFX/SFX-L power supplies to preserve internal space, and consider passive or low-RPM fan curves to benefit from natural convection while minimizing noise.
