There is a problem with the motherboard's rear M.2 slot — the screw hole where the 2280 stand-off would go is blocked, as the stand-off snapped while screwed into it. I think this is fixable with a screw extractor.
Solid build quality and performance all round. It does everything you'd want from a B550 board and with the extra ROG flare.
I would highly recommend this over a lower end X570 board.
Very happy with this.
