As the most significant update of this year, the appearance design of the Mac mini, which has been used for more than ten years, has finally changed - becoming a true "mini host". The "three dimensions" of the new host have been changed to 12.7&amp# 215; 12.7&# 215; 4.97 cm, the previous version was 19.7&amp# 215; 19.7&# 215; 3.58 centimeters. From a visual perspective, 'occupying table area' is almost equivalent to a quarter of the original.
