You wouldn't need to change the bracket and everything, just the FPC is all, the thin plastic Daughter board.
There isn't a tutorial for that specific version that I know of.
There's all kinds of room for LEDs, when you're using 0603 SMT size ones that is, to put it at the top or bottom edge of the PS button. It doesn't have to shine up from under the button to light it up. You can get a 3mm one stuffed in there, but it's more work than it needs to be also.
ah i was trying to figure out how to fit a 3mm one in there, im def going to go with the 0603 SMD now that you mentioned it. i might even get one of those clear start and select buttons off ebay and glow that bitch up, i never even considered using those
thanks a whole lot, you were a big help.
