"Possible to replace glue with magnets?"に関する回答What about magnetic tape? https://www.amazon.com/Flexible-Magnetic-Tape-Adhesive-Projects/dp/B078SZLKRC I have not tried this myself but I will probably try it next time I have to open up one of these iMacs. Although honestly, I try very hard to not bother. The main thing people want is a larger/faster hard drive and it’s better to use an external (in most cases an SSD) rather than going through the hassle of messing with cutting then replying adhesive.
