Hey, Here is my current computer build I use for gaming. I'm looking to convert to an unraid build that has lots of storage that is easy to expand on and to replace my wife's computer with being able to run a 2nd windows box from this.

The links are just exactly what I bought already and have been using. Already have a 2nd video card that would be taken from the current 2nd computer. What upgrades should I look at for converting this build into an unraid? I am looking at buying a single 10tb wolf hd for parity currently as a start and possibly a cpu upgrade.
