Compact Micro-ATX chassis with integrated handle

The Silverstone SST-SG12B-V2 is a small-form-factor case built for Micro-ATX, Mini-DTX and Mini-ITX motherboards. An integrated aluminium handle makes the system easy to transport. The steel body with an aluminium front panel holds an ATX power supply up to 370 mm long.

Drive capacity and GPU headroom

One external 5.25 inch bay sits above three internal 3.5 inch trays that also accept 2.5 inch drives. Nine dedicated 2.5 inch mounts provide dense SSD storage. Graphics cards up to 14.5 inches (368 mm) long and 4.46 inches (113 mm) wide fit, though the manual notes that fan and cage choices can reduce that limit.

Cooling layout and included fan

A 120 mm side intake fan spinning at 1200 rpm ships pre-installed. Two 80 mm slots on the top and rear accept optional fans, and the rear also supports an optional cross-flow unit. The CPU cooler clearance is 82 mm, and front I/O provides USB 3.0, USB 3.1 Type-C and audio jacks.

Questions about this item

Will my existing 3.5" hard drives fit in the SST-SG12B-V2 alongside a long graphics card?

The case holds three 3.5" drives in dedicated brackets; however, the manual notes that drive-cage configuration can reduce the 368 mm maximum GPU length, so plan the layout before buying.

How can I verify the pre-installed 120 mm side fan is running correctly after I build the system?

The included side intake fan spins at 1200 rpm; check fan speed in BIOS or monitoring software and confirm airflow moves from the side panel toward the interior components.

Does the box contain a power supply or do I need to buy an ATX unit separately?

No power supply is included; the chassis supports ATX PSUs up to 370 mm long, so you must purchase one that fits that length limit.
