OrangePi One Duo Case

Well...I did like the original design quite much so I decided to stick to it in other projects I set up in order to tidy up my rack. I am somewhat a bit of an SBC aficionado so expect more to come.
The current design is for two OrangePi One I have sitting in my cabinet, one for Blackhole DNS (https://pi-hole.net/) and one as a spare for future networking tasks.
Both SBCs are independently switchable but yet only do need a single Micro USB. Remember to have a Power Supply with at least 2AMPs t
