I have seen talk about using the iMac as a monitor for the new M1 Mini. What I am wondering, however, is can I use the iMac for the monitor AND use the iMac’s 3 TB fusion drive as an external drive. I do not want to keep the application and OS X software on the iMac.
Finally, if I can should I want to? It seems it would be a lot lass expensive than buying a new 27" monitor and new memory. Data with OSX and application software now almost fills the 3 TB fusion drive. I have almost 2.4 TB photos.
