I have pre-ordered an M4 Mac mini with 24GB memory, 1TB storage and 10 Gigabit Ethernet to replace my existing M1 Mac mini that has 16GB memory, 512GB storage and Gigabit Ethernet. a friend who asyet has no Apple Silicon Mac has expressed interest in my current mini when I no longer need it. He has a 27-in Thunderbolt display to use with it.
