Some notes on fitting the IO panel
You will need to remove the locking bolts from the joystick ports first.
The two rightmost ones are outside the ATX area, so they cannot be fitted. I usually move these to the DVI connector.
(I’ve started to fit the bolts on the DVI connector as well for new boards, these also need to be removed first).
Depending on your case, it may be easier to fit the panel to the board with the four bolts first, otherwise be careful of the alignment of the ring on the SVHS connector – it can cause the panel to bend.
