Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case.

Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

is there any way to replace the I.O without swapping the motherboard?
From cutting through the adhesive to the smoke test this was just under a four hour job for me. One adhesive strip left a complete layer of glue on one side of the screen, and it took me the better part of an hour, about half my supply of wipes, and a plastic razor blade just to clean that one edge up. I’d break the time down as: removing, cleaning, or reapplying adhesives, 2 hours; non-adhesive disassembly, 50 minutes; reassembly, 40 minutes; “oh crap, where’s that tool?” 15 minutes; and about 10 minutes for cleanup, including vacuuming out the fan, heat sink, and vents.
Hi there, I need your professional help. I followed all instructions to change my iMac 2017 27" 5K fusion drive with a Samsung EVO 970 PLUS 2TB (with upgraded firmware) for macOS bootable drive and extra EVO 860 SSD 4TB data drive. Then updated to Monterey. My first test was 1200w 2900r, which was different from the youtube video which was roughly 3Krw. Why was that? Then after a few days of work, the mac froze during youtube watch and again during excel spreadsheet, and restarted with a "?" in a folder. I made an online hardware check all OK, then performed first aid, and again all OK. Then rebooted to the same "?" screen. And then rebooted again and now it works. So far! I see in the system prefs - Link Width x1. I made the speed test again and the reading now is roughly 700rw. Screenshots and sys error report bellow. What have I done wrong? And what to do to fix it all? Thanks!
Did anyone already thought or experienced to just cut out a square at the back of the frame? its not elegant but my imacs back just faces the wall :) for thermal reasons i can imagine just to stick it back.
It's a shame Apple couldn't manage to put this on the front of the logic board--such a pain (by design).
