SG12 (V1)


SilverStone’s Sugo series, since its introduction in 2005, has been the de facto standard for which retail small form factor cases are defined. The introduction of SG12 is both a tribute and advancement to one of the most revered case designs within SilverStone product portfolio, the Sugo SG01. With classic shoebox proportion maintained, the SG12 continues to impress with its ability to accommodate many standard sized components such as ATX power supply and room for graphics cards up to 14.5 inches (368mm). For cooling, side intake fan size has been upgraded to 120mm from 80mm to help cope with future hardware demands. For storage, redesigned internal layout allows for installation of up to nine 2.5” drives. Finished with an aluminum front panel with built-in handle bar, the SG12 is an excellent case for anyone looking to build a semi-portable, compact workstation or a powerful, yet small gaming system.
