With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.

If there is a wire or cable underneath adhesive tape, always pull the tape off first.

Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.

Don't forget to use a ESD Wrist Strap and or ESD Mat; you can fry components by touching the wrong surface or part; don't find out the hard way.
Tell us the Manufacturer of the Logic Board please and the Modell Type
C02SX8FRGG7J logic board
I wonder if its possible to install a newer(2017) Logic Board with a better GPU,CPU and faster USB Ports into my late 2015 iMac 5k.
I mean, to buy one costs around 500$, why not to swap it out and sell the 2015 Board. The Upgrade to
a newer GPU and newer System (USB-C, RAM, CPU) may worth the 500$.
After all one could sell the old Logic Board and gain some money back - don´t you think it is a good deal?
After the Upgrade I could finally use the TB3 for eGPUs and all other Benefits of the newer iMac Board.
I know, I would have to deal with the Ports and do some work on the Body of the Mac, but if this is the only problem, then I
think it is manageble. What I really do not know is wether the 2017 Board will fit in the 2015 Body or not, and wether the power supply is the same or not.
Thank you for Answers, I hope there will be some.
I’d like to know the same thing. Theoretically it’s possible but sounds very weird to be that none tried or ask the same thing. I’d be a very bad thing for Apple
