Ack! We were excited to see this. While not exactly the same, we're building (& shipping!) an RPi CM4 SATA carrier board as well, in the PiBox (https://pibox.io/). Just finishing up the final details of the metal case and shipping out the first circuit boards this morning!
I hope we'll see a huge increase in is-actually-a-real-computer-running-real-software IoT devices once the supply-chain issues start to get resolved. At any rate, we think there is a very bright future for home-hosting and IoT!
