Intel officially launched its new generation NUC desktops, complete with reference-design chassis; based on the company's 6th generation Core "Skylake" processors. Intel launched two main models, which each have variants based on chassis design - the NUC6i5SY, based on the Core i5-6260U processor; and the NUC6i3SY. The two each have variants with a compact chassis, with just enough room for an M.2 SSD (NUC6i5SYK and NUC6i3SYK); and those with room for a 2.5-inch SATA drive in addition to the M.2 SSD (NUC6i5SYH and NUC6i3SYH). NUC boards for the two are available without the chassis, opening things up for custom, third-party cases.
