I/O Panel

Im attemtping to seat my motherboard into my HAF 922, but the I/O panel has some little bendy metal prongs next to each port.. do I have to force the motherboard into the panel or do i break off the prongs?

Don't break them off, but you can bend them a little to get the mobo to seat right.

I had to bend the little metal tab that slid into my ethernet port to get my mobo to fit right, no harm done.
