SilverStone had their Petite Series of super-compact NUC cases on display at Computex. The PT20 is the enclosure made for Intel’s Core Broadwell equipped NUC boards. While the case looks aluminum, it is actually made of SECC steel. It has official dimensions of 125 mm x 50 mm x 110 mm (WxHxD) and features a 2.5-inch hard drive bay and two from cutouts for USB 3.0 ports.
