My desktop's case is a Cooler-Master Storm Scout 2. The removable top panel (the one that exposes fans mounted to the top of the case) often buzzes while my computer is running. I've verified that none of the cables are rubbing against the panel, so it's the case itself that is causing the buzzing.
I can stop the buzzing by pressing on the top panel with moderate pressure, or by tilting the tower very slightly in any direction. If I give the side panel a light whack, the buzzing will sometimes stop for anywhere between 1 and 10 minutes, but inevitably returns.
I've tried hacky workarounds like sticking something under one of the feet to give the tower a slight tilt, but these aren't real solutions. I move my tower frequently (which is why I selected one with a handle), so I'd rather find a better approach that doesn't require keeping the tower in a very specific position.
I feel like there's probably a very simple solution to this problem, but I sure can't think of one. Thanks for your suggestions!

You have something physically loose or mis-aligned somewhere. Make sure that things are screwed in snugly and that any panels or covers fit and close properly.
Go over everything in a methodical way, just to make sure you cover all the bases. If you can't find it, some thin weather stripping might help along panel/cover edges.
