When I setup our DVR in December, I repurposed an old PC chassis with a 1.7 TB disk. It was good enough to convince me that Channels DVR is the right solution for us. My wife and I both use it regularly.
However it has become unreliable due to the age of the hardware (12 years). It looks now like the power supply might have failed. Knowing I can run the DVR software on virtually anything, what is the most foolproof out there? I'm looking for something I can setup once and have it "just work" with ongoing updates and maintenance. Preferably fanless, and I prefer Ubuntu or similar. I don't want something that's going to require a manual power cycle if/when the UPS fails or power flickers or cosmic rays or other strange events.
Also is the Docker image the easiest to setup and maintain, or stick with a direct install? This will be a single-purpose computer. Thanks.
