AMD does not make computer cases. But, if you post a picture of what you are asking about maybe someone can help answer your question.
Also provide more info on your system... INFORMATION REQUIRED WHEN POSTING A QUESTION
I have a cyberpower PC computer which has two tiny buttons underneath a lip on the top of the computer. One changes the colors on the tower (they light up because one side of the tower is clear glass) and one I believe restarts the computer.)
In any event, it's not the right question for the graphics card forum. Good luck.
