Thanks guys. This is all useful info.

Since I started thinking of a solution with all disks manged by Windows, I've also been looking into small server cases (mini-servers?) where one could install a full server (again: Windows Server) and a number of disks (4 at least, I guess).

I wonder if "NAS cases" are what I want, or if they pose any limit when used for full servers.

Just thinking out loud, here. Any recommendation welcome, of course!
