They won't overclock it to any major extent; that's not their game and it's not designed to scale to insanity. But word is the cooling system in the new Mac Mini is pretty nice. At the very least I'd expect it to ship with an M1 Max with both neural engines active (the laptops have one disabled for some reason) and wouldn't put it past them throwing in the rumored (and all but confirmed to exist based on what I know about the architecture) M1 Max Duo.
