Hi Nic,
Please arrange a NUC and keep trying with Netflix. (Since it is an Intel device it should not be that hard to get one for you)
At AnandTech in the Intel NUC review they have the same issues:
AnandTech | Intel's Haswell NUC: D54250WYK UCFF PC Review
If you still cannot reproduce, please let me know if I can provide you with a log or run a test which provides you with the information you need.
This issue is unsolved much too long.
