Maybe I missed it but I would like to replace the art and take apart my Hori Real Arcade Pro 3 that is on the way, is there a thread on this?
I am not sure if there is an official thread, but here are the instructions, I believe, this is how the T5 operates.
Unscrew the 8 screws at the bottom of the case. After removing the panel you will see 6 nuts (no homo). Undo these to remove the decorative bolts which hold your top metal panel down. After this you will want to carefully remove the top panel to make sure not to mess up any wires by ripping them out. I hope this helps.
