Does the job, and very accessible detailed BIOS!
The itx motherboard for its price is pretty good considering the offerings it gives to the consumer, excellent placement of fan connectors, cpu fan, sata, and more but it has a non reinforced pcie connection, along with a very dubious spot for the cmos jumper, and mine didn't come with cmos jumps even on it.

Reviewed in the United States on February 10, 2023
It’s a great value and fits perfectly with ID-Cooling IS-55 CPU air cooler. Nothing fancy for ram/cpu overlocking but gets the job done and won’t disappoint. I paired it with a Ryzen 7 5700X and Powecolor 6700XT in a Ghost S1 case. Any ITX build is a labor of love!
