The issue with what you’re proposing is that it’s a so-called “MOCK”: it isn’t a NUC. It might work fine now, but you aren’t guaranteed it will in the future.
Instead of the current CPU / motherboard combo you have, you need to pick something from this list if you want to be reasonably sure it’ll work and be supported down the line.
And if you’re curious, Roon’s CTO uses a NUC7i7DN* in his personal system.
