I have two NUC’s (ryzen 7 and intel i5) they’re rock solid.

Yes, if this works sure why not. Few years back decent NUC cost was at least 1k$ dollars. And still it is quite small, so you cannot slam 8 ssds in there.

I did use my old PC and it was working very nice with 4 sata ssds, in raid 10.

And as I already said on other comment - in my case power does not matter much. Space too.
