Intel is ready with pre-built NUC desktops based on its 8th generation "Coffee Lake" SoCs. The cases of these NUCs are mosty similar to those the company debuted its low-power "Gemini Lake" based NUCs with, this March. The NUC8i3BEH, NUC8i5BEH and NUC8i7BEH, differentiated by Core i3, Core i5, and Core i7 chips, respectively; come in larger cases to cope with the 28-Watt TDP. In addition to a bigger heatsink, these three serve up a 2.5-inch drive bay with SATA 6 Gbps back-plane, in addition to an M.2-2280 slot that has both SATA and PCIe 3.0 x4 wiring. The slimmer NUC8i3BEK and NUC8i5BEK, differentiated by lower TDP (15 W) SoCs, lack 2.5-inch drive bays. You still get a full-featured M.2-2280 slot. Retailers hint at availability from the first week of August.
