My "used" but sealed 8th gen. NUC i7 arrived in excellent condition with a power adapter, but NO power cord to connect the brick to an outlet. It's unbelievable that Intel did this. The product description needs to reflect the fact that some units do not come with the required C5 type power cord connector. I contacted my seller and they immediately sent me the missing cable at no addtl. cost, which was very nice. The computer is now up and running Linux Ubuntu. Very pleased with the size, speed, and nearly silent operation. Installing a SSD & RAM was a snap as well.
