Welcome here, like most people already expressed, I too like the videos ! If you are into SFF, you are in the right place.
In one of your videos you have what seems like the 4-pin CPU power cable (yellow black wires) connected through two Molex connectors that come from your PicoPSU. You could potentially rewire it to go straight to the 4-pin (possibly sleeve it) so you have a much more clean look in that front area and maybe even tuck the cable underneath the board. This would mean you'd have to desolder the Molex plugs but these are obselete, especially for SFF builds.
