PC Case Silverstone SG13 Mini Tower Black

The SilverStone SG13 Mini Tower is a compact Mini-ITX/Mini-DTX computer case designed for space-constrained builds while retaining flexibility for standard components. With an internal volume of about 11.5 liters and external dimensions of 225 mm (W) x 285 mm (D) x 181 mm (H), the SG13 fits easily into small desks or home-office setups. It accepts both 2.5" and 3.5" drives and is available in black or white finishes.

Advantages

The SG13 combines a very small footprint with support for standard-size parts: it can house a 10.5" (approx. 267 mm) long expansion card, a standard ATX power supply, and an all-in-one (AIO) liquid cooler up to 120 mm or 140 mm radiator size. Front fan support for 120 mm and 140 mm ensures good airflow options for compact builds. Constructed in steel and weighing 2.47 kg, the case balances durability and portability.

Suitable for

• Compact home or office PCs
• Mini-ITX gaming systems with a single full-length GPU (up to 10.5")
• Small form-factor workstation or multimedia builds
• Systems requiring both 2.5" SSD and 3.5" HDD storage

How to use

Install a Mini-ITX or Mini-DTX motherboard inside the chassis, fit a standard ATX power supply in the PSU bay, and mount storage drives using the dedicated 3.5" and 2.5" locations. When installing a discrete graphics card, ensure its length does not exceed 10.5". For liquid cooling, fit a 120 mm or 140 mm radiator where supported or install 120/140 mm front fans to achieve required airflow. Use the front panel USB 3.2 Gen 1 Type-A ports for peripheral connections.

Recommendations

For optimal cooling in tight builds, use a low-profile CPU cooler or a compact 120/140 mm AIO and configure front fan(s) as intake with unobstructed airflow paths; verify GPU length and cable routing before final assembly.
