Repair and tool-selling site iFixIt has done a teardown of the very latest Mac mini and found it basically unchanged from last year's model in terms of repairability. The company revealed that the RAM, hard drive and even the power supply can be replaced or repaired, with only the processor and graphics not able to be upgraded. The teardown also revealed that the new Mac mini still has an extra SATA connection and room for adding a second hard or sold-state drive. The unit received an overall repairability "score" of eight out of 10.
