Building your NUC is easy and you’ll basically only need a screwdriver or two to do it. It’s good to have one smaller and one bigger if you’re installing an M.2 SSD drive as the screw holding the drive in place is quite small.
Instructions are provided with the NUC but if you prefer to see how it’s done have a look at the two videos below. The assembly process has been the same for several years now for all models of NUCs (with the exception of the gaming NUCs) so you don’t have to hunt for a video for the exact same model you bought.
