Need extensive help on modding the Madcatz SE

I was originally going to post this on the absolute q/a thread but I don't want to worry about my post getting buried and stuff.

Also I will be searching the forums later for potential answers, but I just want to get this out there first.

Alright, just acquired my SE case today (well the KE, but same shit).

Does anyone have experience/know of a tutorial with pictures for modding this with a PS360+?

The guy left Start/Select buttons and wires intact, and the headphone jack is still there (though I have no plans on using it).
The joystick mount (the metal panel) also seems to be there.

He took off the turbo panel (which I assume is the PCB originally anyway), so I need a way to fill in that big gaping hole as well as two buttons (8 button is dick). Does anyone know of a way to do this? Don't want to apply artwork and worry about accidentally like, punching a hole through it lol.

First things first I'm going to be painting the entire case black, and apply some custom artwork. After that comes the actual electronics (which I have no experience with).

I have access to a dremel, if I need to dremel holes for a PS3 guide or 360 guide button (or both)... as well as the Neutrik adaptor hole.

Thanks for everyone who contributes to helping me on my first real mod d:
