i have an aspire xdreamer 2 case and i think the side panels are rattling. at first i thought it was one of the fans or my maxtor drive but then i removed both side panels and the rattling stopped. drove me crazy finding out where the annoying sound was coming from but now that i know its the side panels what can i do?

i took the both off but i dont want to leave my PC on without the side panels on the case. any suggestions?
