Solved Are there any 400-series AM4 mATX motherboards that are compatible with M1?

As crossposted in the SFF subreddit, I am wondering if there are any 400-series mATX AM4 motherboards that are compatible with the M1. I just noticed that the official table has not been updated in a while and am considering buying either the M1 or the Raijintek Ophion. I may very well go with the M1 given the extra PCIe slot I would gain over any ITX board and that I would readily fill with a premium audiophile sound card.

Not sure offhand; you'd have to go through the available options and look for boards with 2-3 slots, and then compare the specs to the maximum size the M1 supports (226 x 173mm, or 196mm with the ATX bracket).
