The Machinist B450M-ATX is a very good budget motherboard supporting up to a Ryzen 5 5600X. It’s a white motherboard and it comes with the IO shield, the standoffs (not screwed in the mobo just in the box with it), and also a wifi dongle included with wifi 5. It’s updated to the latest bios so it will support any Ryzen 5 cpu you pair with it.
