Default Isolated sub chassis

i'm in the process of designing my new casework and i have a question about power supply PE and component COM (ground).

if the chassis has PE and i put an isolated sub chassis for the electronics (headphone amp and RPi) do i still need to connect COM to the isolated sub chassis?

the only cabling that will be going into the case is from AC power. the RPi will be via wifi and then straight to headphone amp so no external phono connections. other things such as USB sockets and headphone socket will be isolated from the main chassis.

As a rule, any metalwork unless doubly insulated must be earthed.

isolated 'plate' will be on non conductive standoffs. casework will be made from stainless steel.

or do you think it would be better just to stick too two cases, one for the PS and the other for the electronics with DC power via umbilical?
