Ordered this on June 22 and it was delivered on June 26. Included were the computer, power cord, wireless keyboard, wireless mouse, and USB WIFI adapter.The wireless keyboard required one AAA battery and the wireless mouse required two AAA batteries. The USB adapter for the wireless keyboard/wireless mouse was stored in the back of the mouse where the batteries go.Computer setup was smooth and without any issues. Computer is quiet and fast (whether navigating between different folders or browsing online). Very pleased with this.
