iFixit 카드보드 서비스 쐐기를 사용하는 경우 다음 조립 지침을 따라 조립하세요.

i am glad i have found this guide. Thank you so much for this guide. But i wonder if i want to upgrade my cpu with i7, which i7 model should i upgrade? And after reassembly do we need to make any setups on osx?
And finally; how we can re-attache the screen? Do we need some kind of glue or what?
hi, does anybody know if the graphics card can be upgraded on imac 27" 2012 (emc no: 2546) ?
No not possible… the GPU is soldered to the PCB…. you can only upgrade by sourcing a new motherboard with a better GPU (and you might as well add a new CPU to that as well….
