Apple updated the Mac mini to its inaugural in-house SoC last year, but it is not done with the compact PC. According to a new leak, Apple has finally overhauled the Mac mini's design, which features plenty of ports, a flatter chassis and a new M1X or M2 SoC.

the actual macmini is fine, i was waiting for double ventilation top/bottom of the M1X/M2 also because has shown better perfs respect apple products with the same M1, but M1 of macmini has showed better perfs with a better cooler system.
