For plastic enclosures
Disadvantages: plastic shell color value is too low, too bad feeling. The thermal conductivity of plastics is poor, which makes the machine in running a large number of orders will be rapid warming, speed and life which will in turn will reduce the machine
For metal enclosures
The defect: metal has good heat conduction and conductivity, but because the high density molecular structure has a strong shielding effect on radiation, the disadvantage also lies in its advantages - good thermal conductivity, which makes the fuselage overheated when the processor overheat and feels very hot; shielding radiation may also shield the part. In order to improve network reception capability, external antennas are needed.
