User replaceable SODIMM DDR4
It's been some time since Apple allowed Mac Mini owners to upgrade their own RAM, but the 2018 model brought the feature back to the table.
The Mac Mini uses standard SODIMM DDR4 modules, more commonly found in laptops. The Mac Mini can accept two modules, which combined can be up to 64GB. It's unlikely most will ever need that much, though, and kits are almost impossible to find, too.
A lot cheaper than buying from Apple
When it wasn't user replaceable, if you wanted more RAM you were stuck paying what Apple wanted to charge you for it. And that's never been close to as cheap as you could make the same upgrade for yourself. It still isn't.
When buying a new Mac Mini, increasing the RAM to 16GB costs $200, 32GB costs $600 and 64GB an eye-watering $1,400. You could upgrade to 32GB yourself and save about $400 in the process. Even at the 16GB level, you're saving $100, and that's not an insignificant amount.
Invest an hour of your time instead of hundreds of dollars for the same end result.
