The picture to your right shows what will soon become one of the first commercially available Steam Boxes.
It's made by iBuyPower, which has told The Verge that it hopes to have the device on the market in 2014. It currently runs an early version of Steam OS and, to our mind, looks a little like the PS4.
It's bigger than a PS4, however, and smaller than an Xbox One. It will cost $499 – the same as an Xbox One – and contain a multicore AMD CPU and Radeon 270 GPU as well as a 500GB HDD and internal wi-fi.
Although that won't be enough to offer top-spec performance on the most demanding titles later down the line, it is enough to run all current Steam OS Linux compatible games at 1080p and 60fps.
