Windows 7: Anyone have Emachines EL1850 desktop?? question

if any of you have this machine... I cannot figure out how to remove the PCIe card slot filler panel. I know how dumb this sounds, but it is way less than obvious to me.
I don't want to try "punching" it loose from the surrounding material for fear of bending the frame. I put a little pressure on it and it did not budge.
gotta be something I'm not seeing.

all help gladly welcome!

take a flat bladed screwdriver and a small hammer and start tapping around the edges till you break it loose. A pair of needle nose pliers may come in handy also...
