I just went through this process yesterday, and today wondered why I needed to take all that crap out, because I don’t remember anything blocking the battery removal, that would require removing the speakers, logic board, etc. I think it’s because of the acetone adhesive solvent. It’s powerful stuff that can easily damage the system. Maybe, if you are able to get the battery out without the solvent, you can skip all the other stuff. I will say, however, that in my system, it seemed like the adhesive is real solid. It felt like I was pressing the card up against aluminum studs in the frame, until the solvent loosened it up. If you try to remove the battery without the solvent, be very careful not to use excessive force and warp your frame.
