To facilitate the removal of the keyboard, it is recommended to push the keyboard outwards with one hand through the opening (highlighted in the third picture) located on the backside of the Mini 1000.
While pushing through the opening with one hand, grasp the left upper edge with the other hand and slightly pull the keyboard towards you.
Once an opening has been established, grasp the keyboard and slowly lift it upwards along the upper perimeter of the top edge.
Pry the Wi-Fi antenna connectors (2 total) up off the Wi-Fi board.
During reassembly, remember to correctly connect the antenna cables to their respective terminals. The green labeled antenna is connected to the "MAIN" terminal and the white labeled antenna is connected to the "AUX" terminal.
Upon removing the Phillips screw that secures the Wi-Fi board to the motherboard, the Wi-Fi board should pop up from its top side nearest the antenna sockets.
Grasp the Wi-Fi board and lift it straight away from its socket on the motherboard.
