Review on SilverStone Technology SST-FF81 SST-FF81B 80mm Fine Fan Filter with Magnet Cooling - Black by Todd Lowry

Matches the Corsair 200r case very well. I love that it's magnetized on all sides, with 13 different magnets to help it stick and unfold. It doesn't cover the 200r upper grille 100%, but it's good enough and only leaves a small stripe. Overall, this is a good affordable option that can be used on any metal case. UPDATE: I ordered a second unit to cover the side vents and found that the mesh is actually fabric and can be pulled off the plastic rectangular mold with some force. So keep that in mind. It's okay if you set it and forget it, but if you move around and touch the filter a lot, you might want to choose something else or just be really careful.
