A word of caution when reassembling. Be sure to replace the LCD thermal sensor connector and the optical drive thermal sensor connector with the contacts facing down. They are both very small and easy to overlook the contact points. If either or both are reinstalled wrong the iMac will not power up. You will get a white screen momentarily and then it will go black. I made that mistake and had to go back in and correctly insert them which solved the power up problem.
I successfully put an SSD (mounted in OWC data doubler) into the optical drive slot.
I got slightly thrown for a moment that at step 10, the iMac was apparently rotated 180 degrees. I didn't really want to change my work position, so I turned my iPad upside down to follow the pictures correctly. Not sure why the perspective changed at that point in the manual.
The other "interesting" task was reattaching the LCD, what with the nearby rare earth magnets trying to steal the screws. Having a heavily magnetized torx screwdriver was a big help; I just took a magnet of my own and stuck it on the handle end of the shaft, and then it held the screw enough to make the job possible.
I was quite relieved when my iMac booted after all this. :)
Per error se'm va introduir una targeta portadora de microSD tipus SD a traves de la ranura del lector de CD-DVD.
Seguint aquesta guia perfectament bé explicada i amb les eines adequades, T10 Torx, tornavís de rellotger tipus estrella o philips i en el meu cas dues ventoses solidaries tipus mànec d'enganxar a la paret de la dutxa per no caure; he aconseguit recuperar la microSD, el lector de CD-DVD i el iMAC continua sencer.
Mil gràcies Andrew Bookholt, ets un crack e indubtablement molt bona persona.
