And can you use the internal pulse eight HDMI-CEC? or should I go external just to be safe?

I have the external, I have no idea if there is enough space to get the internal one in...space looks tight. Obviously the wise move would be to just wait and see, but something tells me from the pictures I've seen it would possibly be a struggle. The communication from pulse 8 is pretty good, so I'm sure they can let you know sizes.

Watch out the pinouts! Intel Haswell NUC provide different pin layout than other motherboards supported by HDMI-CEC adapter. I'm confused because of missunderstanding in the Intel's documentation. Ones they write SMBUS but in table is DMIC or sth like that. Anyway the standard Pulse8 cable is not correct for this motherboard.
