Question What is this raised square piece of plastic behind the front bezel for?

[OffAgainOnAgain]

Pulled out the front panel I/O connections to diagnose clicking noise coming from around the mic/audio jacks and noticed this raised piece of plastic behind the front bezel with a zig-zag thing on top.

The tower is a Corsair 750d and that raised piece of plastic with the zig-zag rests right in front of the reset button, which is next to the audio ports that I heard clicking.

Someone said that the zig-zag thing was a spring to hold the reset button in place. But what about the raised piece of plastic underneath it? Is it some kind of heat sink?

Looks like a power or reset button for the front panel, the raised plastic is to prevent the button from falling into the case when upright.

You might want to take a picture of the bezel from afar.
