Compact server chassis for ITX builds

The Silverstone SG16B is a black mini-tower designed for Mini-ITX or Mini-DTX motherboards and an ATX or SFX-L power supply. It targets builders who need a small-footprint server or workstation that can still house a full-length graphics card. The steel body and compact layout make it suitable for space-constrained racks or desk-side deployments.

Upgrade path from smaller SFF cases

This chassis replaces enclosures that limit GPU length or radiator support. The jump is worth it when the build requires a graphics card up to 275mm long or a 120mm all-in-one liquid cooler. It also adds a 3.5-inch or 2.5-inch drive bay plus a dedicated 2.5-inch bay, removing the storage ceiling found in tighter designs.

Straightforward assembly with a rear cut-out

Installation is simplified by a CPU cooler cut-out on the motherboard back plate, allowing cooler swaps without removing the board. Front I/O provides two USB 3.0 Type-A ports and a combo audio jack. Builders must verify their GPU length and radiator thickness against the 275mm and 120mm limits, as exceeding either will prevent the side panel from closing.

Questions about this item

Will a 275 mm graphics card fit inside the SG16B?

Yes, the chassis supports standard-length expansion cards up to 275 mm.

How do I install a 120 mm AIO radiator in this case?

Mount the 120 mm radiator in the designated area; use the CPU cooler cut-out on the motherboard back plate to attach the water block without removing the board.

Which drive bays will I need to replace if I add more storage later?

The case provides one 3.5" or 2.5" bay and one dedicated 2.5" bay; additional drives require using those existing slots.
