Not necessarily, to me it's very feasible in the same way every high end dock is doing: use a high bandwidth, readily available connector like usb 3.2 to operate the whole thing. OP doesn't need to provide anything other than the metal frame, but my use case was to have some sort of way to setup a usb hub inside where I could plug
this to power a fan , obviously have access to USB ports if possible but not necessary, have added storage in the base (external 2.5 SSD mounting spots maybe ?) nothing crazy.
It's very much more convenient to just unplug that USB C cable than to have to whip out the screwdriver when detaching it.
Maybe I'm missing something but it seems fairly doable to me, not saying OP has to take care of all that he would just provide the frame with these uses in mind and everyone is free to use it however they want.
