I have a Mac mini that still had upgradable ram, and was able to be kidded to add a second hard drive. I put 32 gigs of ran and an 1 tb ssd into it. I’ve had it for roughly 7 years. Any current Mac mini is a downgrade except in processor speed.
Would complain that nothing is built well / to last any more... but was recommended a NUC, and now it's my new Mini. Absolutely love it.
Enjoy that while it lasts... Hackintoshes are going to be a dying breed in two years.
