So, from looking around the forums, it appears that there used to be a self-install option that was removed because people without experience were messing up their systems.
Is there any way I can request just the board for a self-install? How much would the board alone cost? I would take full responsibility for damages, of course.
I have experience doing these sorts of mods and have actually taken apart my own 3DS quite a few times to add some hardware in it. I'm confident I could put it in no problem.
