Do I need to move the method of creating a "factory" into a separate class?

Question

Design patterns

//Controller:
  public function show()
  {
    //Нужно ли выносить этот участок
    if ('Linux' === 'Linux') {
      $factory = new LinuxFactory();
    } elseif ('Win' === 'Win') {
      $factory = new WinFactory();
    }
  }
