The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash, and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion.
The full PCIe slot on those boards is just gold. I have a NanoPi M4v2 that also has PCIe in a M2 slot, used a cheap board to get 6 sata ports out of it.
I actually got the B version but there is an adapter if I change my mind down the road. I wanted the wireless and ir sensor
