Just built a NUC 6i5
My wife needs a new computer, and this sounded good. The price premium isn't much over a case, PSU, and so on.
16GB RAM and 500GB M.2 SSD (and I put an old 128GB Samsung in also).
Other than some Win10 drives not wanting to work it was slick and easy.
Hung it on the back of the monitor and away we go.
