After reinstalling my PC 2 times, I think the 3rd is the final one. I decided to create a new center console for the rear seat, which will house my PC. I recycled the piece that holds the MoBo for stability, but I am not sure about the PSU.

Should the PSU be seated on heavy plastic (which the rest of the PC is being designed out of), or should I cut a metal piece for it to set on likr the MoBo?
