Mmm you can upgrade the ram but you need to unglue the screen.I know. The 1TB I can live with, but more worries about not being able to upgrade the RAM. The 2020 iMacs are at least twice the price on the second hand market here. Debating with myself if I should bother with this iMac Pro or not😬
It's not a very big deal if you have done it before... But if it's your first time, it's a bit scarry especially as it's an imac pro...
