Superb build quality, lots of usable features and looks great. The USB C front IO connector is one of the many reasons i went for this over other brands. Its GEN 4 PCIE for both the PCIe slot AND front M.2 plus a rear M.2 at GEN 3 make this an extremely capable and fast board. Good power delivery and semi active VRM cooling are nice to see and the layout of the board is well thought out. Its a superb board and im very happy i went with this over Gigabytes X570.
Bulding my first ITX with AMD, the motheboard feels solid and premium. Np problems with my 3700X and the USB-C front panel is very welcome too.
