This is the one I have but it looks like it's not being made anymore. It was like $130 or something when I bought it. https://www.amazon.com/ASRock-Motherboard-J3455-ITX-Quad-Core-Mini-ITX/dp/B01MPWDCLE/ref=sr_1_1

Something like this looks like it would work well, though you're paying for Windows 10 and potentially a small SSD you don't use if you intend to swap that out: https://www.amazon.com/Computer-AWOW-AK34-Ethernet-Bluetooth/dp/B082KR9KX5/ref=sr_1_5

That was like the top result I'm sure there's better choice out there. Long story short, what you picked is overkill but if $$$ is no object, it looks fun.
