These are pretty small, though a bit on the pricey side:

Thanks again for the input everyone. After searching around with this advice I've narrowed this down to two systems:

Pricier but with 10GbE:

More reasonable pricing but less power:

As long as the 2nd option wouldn't struggle with virtualization and databases, this seems like a good fit. Thoughts?

Hey OP, depending on what Gen Nuc you have ( I have the 6th gen-core i5-66260u) You can go with the XeonD-1518 with 10gbe that /u/Netwerkz101 linked or you can go with this XeonD-1528 which has a better passmark score than both the 6th gen Nuc and the Xeond-1518 and has 2 10gbe ports as well. Either way both don't have the same single threaded score as the I5-6260u but they have multiple ethernet port. I think you might have to weigh your preferences but I'm just throwing this out there so you know what your options are
