Great guide, went well for me. While I was worried about steps 6, 10, and 13 (the unplugging parts), the only point that gave me some frustration was putting one of the rubber feet back on. I still don’t think I got it back on quite right, but that doesn’t seem like the most consequential issue.
After some trying with tools, I think I might have ended up pulling everything up (gently!) by finger. They all came off fairly easily, straight up. I think the one that gave me most resistance was the LED wire. I certainly reattached them with my fingers after cursory attempts with tools. It felt good to me to get the biofeedback of feeling them snap firmly in place.
It wasn’t so hard pushing the motherboard out; the main thing seemed to be just positioning my fingers in back so that I wasn’t pushing forward with some fingers and back with others.
At the end, I went the screw-first route for putting the wifi antenna back. Just leave it loose enough to make a tiny adjustment to get the plug in position.
