After removing two screws, the fan can be lifted out to access its power connector.

The connectors inside this machine look pretty consistent with those found in Apple's current product lineup. Nothing too new here.

All three fan screws are isolated with rubber dampers; a feature not seen on older apple machines. Low noise and vibration are big selling points for Apple these days, and the new Mini's idle emission of 14 dB is a testament to those design goals.
