@SSD I appreciate the feedback! I was considering going with what you have since you had no issues with your setup. I was looking at the 7920X also, I think it's the best bang for the buck. The board that I was looking at was the supermicro C9X299-PGF; it's a new board for them and I read quite a few places that supermicro was headache free solution with unRaid. After seeing your post, I reconsidered the Asrock and leaning in that direction instead. I want something that will work and will be headache free. I don't use plex and all the other entertainment docker containers etc.. that I've seen others using. I just plan on using it to run whatever OS I want to run for work, and in some cases I might want to run multiple at the same time for testing and mock deployments. As long as I can run linux, windows, and mac and be up to date for years to come, that's the most important thing to me.
I'll be price shopping now and start collecting stuff as I run across good deals. 64 gb of ram is plenty for what I want to do also, it's the graphics cards that are going to be tricky. I want to pass through at least 3 cards to 3 vm's that I can fire up anytime.
I will post back as I put this together and let you know how it turns out.
Thanks again!
