The Turing Pi is an awesome Mini-ITX board that allows you to slot up to 7 Raspberry Pi compute modules and have them each share the same ethernet cable and power supply. It's great for Homelab and testing out things like containers. This is the first video featuring the Turing Pi, more to come! Let me know if you'd like to see tutorials for the Turing Pi.
