Intel could be moving over to socketed designs with its next-generation NUC 12 Extreme Mini PC as a leaked picture shows an LGA 1700 socket Alder Lake CPU equipped on the Compute Element.

Not to be mistaken with the NUC 12 Enthusiast 'Serpent Canyon', the NUC 12 Extreme will be a whole different beast and come equipped with the Compute Element module which houses the CPU and PCH on its own dedicated add-on-board. The NUC 12 Enthusiast is likely to retain BGA form factor for Alder Lake CPUs while the NUC 12 Extreme is going to be the first NUC to ship in socketed form factors.
