Upgrading the 2017 27" iMac CPU
Since its release, the new iMac 2017 5k can have many things upgraded, as iFixit has said in the teardown.
This video shows how to upgrade the CPU, Ram and the SSD: https://www.youtube.com/watch?v=knMM9dRwIH4&t=452s
So I was thinking here: is it possible to replace the i5-7600k or the i7-7700k to the new Cannon Lake i5-8600 or i7-8700k (both have same socket and same power consumption!), so a 2017 machine can become a fast 2018 one?
