I'd be better off buying an Asus TUF.

Not the best value for your money.
Beautiful
Supports Wi-Fi 7 and Bluetooth 5.3
3 M.2 NVMe slots
Pretty decent built-in audio by motherboard standards.
Terrible BIOS, questionable prospects for updates.
Lack of overclocking settings except PBO and XMPEXPO.
The fan curve setting does not work with DC fans; they will always run at 100% regardless of the curve settings.
