ASRock B450M-HDV R4.0 AMD B450 Socket AM4 Micro-ATX Desktop Motherboard

This board is fantastic value, and easy to set up with everything I needed in the UEFI menu. I haven't tested it with a higher-power CPU than an Athlon 220GE. There are plenty of ports (I specifically looked for D-SUB for an older monitor). Overall I'm happy with it for a budget build. The smaller CPU power connector does mean I wouldn't trust it with a 120W part.

I bought a B450 motherboard specifically because I had an old Athlon lying around and someone needed a computer. So far it works well. It's only a 35W part, so I don't expect any issues, but it does look reasonably built, and has lots of features.
