The Silverstone Sugo 14 supports two sizes of motherboards, the popular Mini ITX form factor (shown in dark blue) and the much rarer DTX form factor (shown in purple).
The case has mounting points for one 120mm fan at the top of the case and one 120mm fan or radiator at the rear of the case (shown in yellow). The only type of power supply that the case supports is the common ATX size (shown in light blue), though SFX and SFX-L power supplies can be used with an adapter which is not included.
The bracket on the left side of the case can hold a variety of different hardware. The front section (shown in orange) can hold one 5.25″ drive bay, one 3.5″ hard drive, one 120mm fan or radiator, or one half of a 240mm radiator. The rear section (shown in red) can hold on 3.5″ hard drive, one 120mm fan or radiator, or half of a 240mm radiator.
There are three 2.5″ drive trays (shown in green), two at the front of the case and one in the center of the case mounted next to the power supply.
The Silverstone Sugo 14 has a generous amount of space for graphics cards (shown in light green). The maximum dimensions supported are 330mm / 12.99″ long, 148mm / 5.83″ wide, and three slots thick.
The maximum power supply length (shown in light blue) that the Sugo 14 supports is 150mm / 5.9″. The case can fit air coolers (shown in gold) up to 182mm / 7.17″ with the top fan removed. 240mm water coolers need to have a water block height (shown in red) of 55mm / 2.17″ to avoid collisions between the top of the block and the bottom of the radiator.
