I got this while trying to create a plex server. There were a few issues, mostly with disk access to the Plex server, that you had to solve, but that's not a Pi issue, it's Linux. The operating temperature is not too high because it is only streamed. Keep in mind that for a Plex server, this can only send the original stream. If your device doesn't support the codec or compression and requires Plex Server to transcode, it won't work, so make sure your device can handle the streams. The newest Rokus do a great job with H.264, the older ones don't. FYI, some Blu-rays are in VC-1 format, which Roku can't handle. I've only streamed up to 1080p so can't say how it will handle 4K. It's best to keep it close to the router unless it's hardwired to it. Because of its small size, Ethernet and USB cables can be a bit tight. This is the best streaming server deal you will ever find. This comes with an asterisk with no transcoding, but as long as you have hardware/devices that can handle the original stream it will work great.
