Piixl has debuted a PC called the Jetpack that runs on Steam OS, and fits flat behind a flat-screen TV to act as a SteamOS gaming machine. The machine utilizes an open hardware platform that allows the user to customize their experience. Starting at $1,000, it represents an attractive, Steam-based gaming and media-viewing option in the living room for those already baked into the system, and for those who want a set top box that doesn’t disrupt the space.
