ASRock B850I Lightning WiFi

5.9/10verdict: good, not the best

This is a Mini-ITX AM5 board for people building a compact system on the B850 chipset. It suits builders who want a PCIe 5.0 graphics slot, a Gen5 NVMe drive and BIOS Flashback in a small footprint. It is less suited to anyone who needs Wi-Fi 7, many rear USB ports or more than two memory slots.
