I did some Googling and the general consensus seems to be stay away from the Chinese boards, while some have no issues, many have and don't recommend them. I guess my question is why go with x99 at all? The technology seems to be almost 10 years old yet they seem to have a pretty large fanbase and are regarded as reliable workhorse motherboards. Are you looking for a dual CPU high core count solution? What is your budget? Is power consumption important? Have you looked into AMD EPYC solutions? What kind of case do you have in mind?

I've had he worst experience with Netgear network equipment, I've had more of them die than any other brand, they are garbage IMO, I don't like anything they make.
