New Intel NUC 10th Gen NUC10i3FNK First Look-Simply NUC – Next Unit of Computing (NUC) is a line of small-form-factor barebone computer kits designed by Intel. The NUC has had eight generations so far, spanning from Sandy Bridge-based Celeron CPUs in the first generation through Ivy Bridge-based Core i3 and i5 CPUs in the second generation to Gemini Lake-based Pentium and Celeron CPUs and Kaby Lake-based Core i3, i5, and i7 CPUs in the seventh and eighth generations. The NUC motherboard measures 4 × 4 inches (10.16 × 10.16 cm).[1]

The barebone kits consist of the board, in a plastic case with a fan, an external power supply, and a VESA mounting plate.[2] Intel does sell just the NUC motherboards, which have a built-in CPU, although (as of 2013) the price of a NUC motherboard is very close to the corresponding cased kit; third-party cases for the NUC boards are also available. – https://en.wikipedia.org/wiki/Next_Unit_of_Computing
