What a mess!
The display goes back here
The display back in place

Be carefull not to pinch the cables under the metal bar!
Now that is better!

Now the power supply which we had to losen to get to the screws of the keyboard
Be carefull not to pinch the aftertouch cable!
Do not put the screws of the keyboard back in place yet!
The card holder
The audio board still not back in place, rather in the way...
Finally the audio board is fixed
The card PCB
Now the shielding, fixed with some of the keyboard screws
Now screw back the keyboard
Lots of screws there...
Make sure that all the cables stick out here
Now put the paper shielding back
Right side
