I've used this Nuc box before, and it's a great item, but I've never had to put it together until now. Perhaps it's me but I found it really difficult to completely construct the SmartNuc box (an irony there?) even with the PDF images to guide me. I also suggest that a printed PDF be provided when the box is purchased or posted rather than rely on the user downloading the PDF. A video (utube?) of how to construct it may also be of use.
