Valve first revealed the Steam Machine in November with a host of different faceplate options in different colours and materials, but the one that caught my attention was a complete e-ink screen faceplate dubbed the "inkterface", which Valve rigged up to show test progression, CPU/GPU temperatures and other metrics. Now that the Steam Machine is in the wild, Valve engineers have released the necessary CAD files, firmware and software for you to build one yourself with a 3D printer and a short list of other components.
As well as those necessary files, there's also a comprehensive set of documentation that explains the process, including videos that go over the physical assembly of the device and uploading the provided firmware. Most of the process is fairly straightforward, but there are some steps requiring soldering and other slightly fiddly tasks. (I'm fairly confident that we'll see third-party sellers on places like Etsy selling finished boards at some stage if you don't fancy the assembly work, and Steam Machine accessory makers Jsaux also seem to be preparing a retail version.)
It's very cool to see Valve continue to offer its designs to the enterprising public, and I'm looking forward to seeing what other ideas the community comes up with as more people receive their Steam Machine orders.
Have you managed to order, or even receive, a Steam Machine yet? Let me know in the comments below.
