The original Raspberry Pi may have been revolutionary to makers, but it took off with PC enthusiasts as well. Thanks to its ability to double as a dirt-cheap home-theater PC. That allure may have waned a bit in recent years as dedicated devices like the Chromecast hit the streets at similarly low prices, but using a Raspberry Pi as a media-streaming box still offers far more power than those streaming-centric sticks, especially if you have a sizeable local media collection.
There are a slew of HTPC-centric Raspberry Pi operating systems out there, each revolving around slapping your HD videos on the big screen. OSMC and OpenElec are two such choices built around the popular Kodi media center software (formerly XBMC), while RasPlex transforms your Pi into the ultimate Plex streaming box.
