I have a Bitfenix Prodigy m-itx case and I already built my system into it. I wanted to clean it a month later, but when i tried to take out the right side panel it wouldn't budge. When i finally got it opened it nothing seemed out of the ordinary. When I put it back on it got stuck again. It seems the top of the panel is stuck the bottom seems fine. The left panel is fine. Please help!
