Quite a nice board!
For RPi CM4 Gigabit Router Baseboard with NVME
Picked this up to pair with a spare CM4 I had. Built on the instructions to create an image that worked to my needs. (IE: You will not be able to install kmods from opkg because of the custom kernel, so include what you need in your build). I threw in two spare NVME SSDs I had, using one for docker containers, and the other as a NAS drive. Easily handles my gigabit internet. Impressive bit of kit for the $$$.
