Are you looking to try SteamOS or have your own custom SteamBox? We have the knowledge to build around a variety of budgets and offer systems in a multitude of sizes to fit any room in the house. Prices typically range from $700 on up based upon configuration options and will include a dedicated Nvidia GPU which provides the best SteamOS experience.
SteamBox takes 3 to 5 days for assembly and pickup.
Many independent games are already compatible with SteamOS such as those purchased through the Humble Bundle collections. Humble Bundle allows you to purchase a nice group of games AND donate to charities for any price you wish to pay. As long as the Linux (penguin) icon shows by the game it will work on SteamOS.
