So this board is really a challenge to flash. I had to power cycle dozens of times before I could get to change the bios to support my cpu. I contemplated returning it after growing tired of the reboots but eventually I got it flashed to a lower bios. If you're lucky to have it working, don't update the bios unless it specifically is for your cpu.

Surprising amount of features for a mATX board. 2 m.2 slots, 1 PCIe wi-fi card slot, and PCIe Gen 4 support are all very nice things to have.
