Mac mini 2014 to 2023 hardware compatibility

Please ask a specific question. If you are asking if you can use your old peripherals, be specific. Such as, "I have a Logitech USB A mouse, can I use this with the new M4 Mac Mini's?" We are NOT mind readers so we have ZERO idea what peripherals you may be referring to!

and if you mean opening up and interchanging components inside then that would be a global no go
