How to remove the power socket from the back case?

I’ve recently gutted my iMac and turned it into a display with a display board. Currently I have the power and display cables coming out the RAM door, but I really want to have all the cables come out the power socket, however I can’t figure out how to remove it. It’s plastic, so I know it’s a different material and not part of the chassis, but I only found 2 screws and removing them did nothing. Anyone have to do this recently or know how to do it? Everything I find online talks about removing the power supply or the power cord, but those are done.
