Here we recommend a Pioneer X3, there are four front USB. Online reported 266 yuan (including power), I recommend the empty box, the box is indeed good, the price is estimated to be 150 can take (this price is sold business profits are good, installed machine does not make money on the chassis money is no money, cut the price of the hands of mercy). The power supply with the box is not good, and find a separate Air Jordan it.
