Computer case SilverStone ALTA G1M microATX, white

The SilverStone ALTA G1M microATX case in white is a compact chassis designed for small-form-factor desktop builds. Constructed from durable materials, it balances internal space and external footprint to accommodate mainstream microATX components. Front-panel connectivity includes one USB 3.0 and two USB 2.0 ports for peripherals and data transfer. The interior supports up to six case fans for flexible airflow configurations and can house two 3.5" drives plus two 2.5" drives. Graphics cards up to 320 mm long can be installed, while the overall dimensions of 390 mm (H) x 210 mm (W) x 450 mm (L) make it suitable for desks with limited space.

Advantages

The ALTA G1M offers a compact footprint without sacrificing component compatibility, supporting multiple storage drives and a full-length GPU up to 320 mm. Native USB 3.0 front I/O provides faster connection speeds for external drives and peripherals, while two additional USB 2.0 ports increase connectivity options. Support for up to six case fans allows for customizable cooling layouts to match different performance and noise priorities. The white finish provides a neutral aesthetic that integrates with a variety of setups.

Suitable for

• Home and office microATX desktop builds
• Compact gaming systems with single GPU up to 320 mm
• Storage-focused builds requiring multiple 3.5" and 2.5" drives
• Quiet or high-airflow configurations using multiple fans

How to use

Install a microATX motherboard and standard ATX power supply following the case standoff positions and cable routing channels. Mount storage drives in the designated 3.5" and 2.5" trays, and secure the graphics card in the PCIe slot ensuring the GPU length does not exceed 320 mm. Configure fan placements to create an effective airflow path from intake to exhaust; the case supports up to six fans so you can prioritize intake at the front and exhaust at the top/rear as needed. Connect front-panel USB ports to the motherboard headers during assembly and route power and data cables neatly to maintain airflow.

Recommendations

For balanced cooling and moderate noise, use a combination of two front intake fans and one rear exhaust fan, and consider adding two top fans if additional exhaust is required. Use a quality low-profile CPU cooler or a compact AIO that fits within the case's internal clearance. When installing multiple mechanical 3.5" drives, ensure good airflow around drive cages to prevent heat buildup. Verify GPU length and PSU dimensions before final installation to guarantee proper fit.
