I will 100% have questions, this is going to be my first mac computer and my first time doing upgrades to a system, i'm a total noob but I usually catch on pretty fast.
That sounds scary... First time Mac user and first time upgrades 🙂
It is one thing to do experiments with peripherals, but if you are going to pull the mini apart to do SDD upgrades etc then do a lot of research on watching vids and close-up pics. It is easy, but many still rip off parts here and there.
Good luck and welcome to the world of Mac computers.
