Ordered the NUC and memory/SSD separately. Very straightfoward and simple to add memory & storage (just YouTube it !!!). Installed Windows from a usb & it just works perfectly. Pretty quick for anything you throw at it. Haven't used it for gaming but very satisfied with the overall performance. Perfect for a small tight office space. Can actually be screwed behind the monitor. Going to order couple of more NUCs given the overall performance. Love it !!!
