With all due respect to your quick reply, it was not correct.
Perhaps I am to blame for not being clear on my question, but when I received my nuc7i5bnk today and went to take the motherboard out of the case, there were THREE wires going from the board to the case.
1) Wifi connector/antenna (as stated in your reply)
2) LED wires attached to the front panel
3) Microphone wire also attached to the front panel
I unclipped the wifi antenna, and then proceeded to pull the other wires off the board (plastic harnesses were easy to disconnect) as I will not be needing them.
No harm, no foul with regard to your reply... luckily the attachments are not crucial for the operation of the NUC.
However, I certainly hope that more accurate answers would be forthcoming in the future!
