HP Pavillion P6774y (circa 2010 or so) desktop.

I was replacing the dedicated graphics card and this fell out.

It looks like it frames the inside of the four slot card panels.

It’s some kind of wafer thin, flimsy, shiny metal.

The only card I have installed is the GT 1030, which replaced an older card.

Just wondering what this is, what it’s for, and any problems if I just leave it out?

Thanks for any help! wave
