Okay, looking even better. This is from zdnet:
MEMORY TO 64GB
Memory, which previously maxed on the Mac mini at 16GB, can now be configured up to 64GB. The base model ships with 8GB RAM, but Apple specifically mentioned that memory is on SO-DIMMs.
I reached out to Apple about this and was told: "Yes, Mac mini is configurable up to 64GB and uses industry-standard DDR4 SO-DIMMs. While we don't consider the memory directly end-user accessible, service providers can access the internals of the Mac mini to upgrade the memory."
This is the best of both worlds, because Apple's RAM upgrades cost $200 to go to 16GB, $600 to go to 32GB, and a whopping $1,400 to go to 2666MHz DDR 4-based 64GB RAM.
If RAM is upgradeable after purchase, this is a big thing. A quick look at the Crucial site today (RAM prices change constantly) show that that same 64GB upgrade can be had for $879, $521 less than Apple charges. Even better, it means you can get an affordable Mac mini and later, as your needs change, can grow your RAM footprint.
(Okay. Plowman again....)
Crucial and other sites may put out some hyper-detailed instructions for tear down and upgrading. As of this writing, Crucial says it has no upgrades for a Mac Mini Late 2018. But hey, it was just announced this morning.
