HI, the NUC is a DCCP847DYE and playing an important part in my familys life as an HTPC running openelec. It runs happily of a USB key and its that or the RF adapter (if it would work in a metal box) for my keyboard id like to take internally.
The external USB ports are used currently used by the USB key, RF receiver and an IR receiver (something that would be a great addition to a future NUC model) .
One other point id ask you to pass on that could be improved is the lack of ability to power on from cold via USB as currently I have to use suspend.
