PLEASE OBSERVE: The image of the left speaker used is NOT for a 2011 model. A 17inch MacBook Pro A1297 - LEFT SPEAKER + MICROPHONE - 2011 has IDENTIFYING NUMBER: Apple Part #:922-9821, 922-9822. And its COMPATIBILITY: 17 inch MacBook Pro Unibody A1297 - Early 2011 MC725LL/A 2.2 i7 - Early 2011 MC725LL/A 2.3 i7 - Late 2011 MD311LL/A 2.4 i7 - Late 2011 MD311LL/A 2.5 i7

not on my 17” late 2011

Looking at the cable socket towards the DVD drive - to the left of the cable socket there is a small rectangular, transparent plastic piece glued to the print board. Its function is to apply pressure to the left of the plug, so that it stays in the socket. Even if you can relatively easy unplug the plug from the socket, this piece of plastic makes it impossible to re-enter the plug into the socket. So, if you can do your thing without un-plugging this cable, you are more safe.

Also, IF you decide to take the plastic piece off and glue it back on, face your tool away from the resistors and towards the DVD-drive. I did not and sheared off 3 resistors from the motherboard. Result = Dead machine. Costwise I cannot defend having it repaired, so am shipping it off in parts, as everthing else works.

But the 2 GPUs DOES make it a nifty little machine - even past Apple and general progress killing off El Capitan.
