DIY Netflix and Spotify in one. You need hardware to run it on. So a computer and storage for the media. You could try it on any computer. For real use, a dedicated machine (doesn’t have to be expensive) is ideal. For example, I have a ThinkCentre 715q with 4 disks attached to it in a cardboard box running it. You can watch and listen to your stuff from anywhere. Your phone, laptop, desktop, smart TV, Chromecast, etc.
