Lego Terminator T-800

Late in the first film, the Terminator is stripped of its organic elements by fire. What remains is the machine itself, in James Cameron's own words "a chrome skeleton, like death rendered in steel." In the later Terminator films, armies of endoskeleton-only Terminators are seen. They are visually identical to the one in the first film, and feature prominently in the "future war" sequences of those films.
CPU
The Terminator CPU is a room-temperature superconducting artificial neural network with the ability to learn. In Terminator 2, The Terminator states that "the more contact he has with humans, the more he learns." In the Special Edition, he says that Skynet "presets the switch to 'read-only' when Terminators are sent out alone", to prevent them from "thinking too much". Sarah and John activate his learning ability, after which he becomes more curious and begins trying to understand and imitate human behavior. This leads to his use of the catch phrase "Hasta la vista, baby." A line spoken by the Terminator at the end of the movie shows that Terminators have the potential to understand emotion: "I know now why you cry, but it is something I can never do." Sarah muses in the closing narration that the Terminator had "learned the value of human life". This emotion was so strong he was even able to defy John Connor's orders, thus defying his programming, for the greater good.
