Everyone has different financial constraints and while this M2 cpu Mac Mini is a solid machine, $370 (8GB/256GB) for a used with 90-day Woot warranty deal would give me pause. When a brand new latest gen M4 cpu Mac Mini with twice the RAM, more ports, two of them more conveniently located on the front and full Apple 1-year warranty is pretty regularly available for $499 or less ($599 MSRP). Two years/two CPU gens newer typically means two more years of MacOS support.
The 512GB version at $400 was more interesting due to Apple’s insane ripoff storage upgrade premiums (+$200 at retail to bump from 256GB to 512GB), but it is no longer available.
These days 256GB of storage might be fine for most folks since everything seems to be in the cloud. For reference, I’ve been using a MacBook Air with 512GB of storage for four years and am currently using only 120GB of it. About 75GB is taken by MacOS and System data.
