Valve announced an interesting add-on for anyone interested in in-home streaming for their PC games: Steam Link. These $50 boxes (in the US, international pricing is TBD) will stream content from your PC or Steam Machine, as long as they're on the same WiFi network. Adding a Steam Controller will cost an extra $50 when they launch in November, and can handle gaming in 1080p at 60Hz with low latency.
I know that 'Steam Machines' and LRPC's are becoming a bit of a thing nowadays, but to me this sort of solution is a much better way of getting a PC into the living room. It's far cheaper than building an entire new computer, a local network will have the bandwidth and low latency necessary to stream games, and you can keep all of your content/hardware/PC budget centralized in one build.
