Three generations that look alike outside and differ a lot inside. The difference that really matters: on the M4 Mac mini the SSD is a removable module again, while on M1 and M2 it is soldered.
And one thing can save you the whole bill: if yours is a 2023 Mac mini with an M2 chip that will not power on, it may fall under a free Apple service programme that is still active.

The fact worth money, before anything else. Apple runs a service programme for 2023 Mac mini units with an M2 chip that no longer power on. It covers units manufactured between 16 June 2024 and 23 November 2024, eligibility is checked by serial number on Apple's page, and the cover lasts three years after the unit's first retail sale. Service is free at Apple or an authorised provider. Apple notes the programme «does not extend the standard warranty coverage».
M1 and M2: nothing to upgrade inside. iFixit's M2 mini teardown states that «the CPU and storage are both soldered to the logic board and not user-upgradeable». iFixit scores the M1 mini 5 out of 10 and the M2 mini 6 out of 10.
The M4 mini changes things, but less than it seems. iFixit confirmed that «it's possible to pop the SSD out after removing a screw, and then switch in a higher capacity one» — while warning that «the SSD's proprietary format makes aftermarket upgrades tricky»: Apple Configurator pairing is required, and M4 and M4 Pro drives are not interchangeable. The RAM stays soldered. iFixit score: 7 out of 10, marked provisional.
Otherwise the mini is a small machine with tight airflow. We recommend a clean and fresh thermal paste every 18–24 months — our recommendation, no manufacturer publishes one.
