I just want to share my opinions of this board, now that I've built one system using it. Here are a few of my impressions:
Linux support:
It seemingly works fine with Linux (Ubuntu 20.04), it has been running without issues for three weeks. I also ran it for a day with Prime95 and Unigine Valley as well, with no stability issues.
If someone has something in particular they want tested, let me know.
IO support:
While I haven't tested Thunderbolt, I want to emphasize the limitations since this isn't well described in the review; Thunderbolt shares bandwidth with the bottom PCIe x4 slot, so read the fine print in the manual before purchasing if you plan to use Thunderbolt. This is relevant for content creators attracted to this board due to Thunderbolt, thinking this will be great for an affordable "workstation", but if you want to be able to add a 10G Ethernet card, then you probably should look for a HEDT board instead. This is one of those edge cases where mainstream platforms may come up short for some (semi-)pro users.
The two x1 slots also share bandwidth with the second M.2 slot, but this is pretty normal.
Overall impressions:
Building with this motherboard is pretty normal and hassle free.
I especially appreciate the BIOS FlashBack feature, which was one of the selling points for me. While Ryzen 5000 worked out of the box, this is still valuable for future CPU refreshes or failed BIOS flashes.
This is no cheap board, but probably will be my go-to board if I set up more AM4 systems.
One extra x4 PCIe slot or M.2 slot would have been appreciated, but that's a limitation of the platform.
