As you’re obviously no american, you also know that even if you’d pay netflix (for the FULL price i might add) you only get a fraction of what they got and not a penny discount for it. Sorry, but no. If you want my money, OFFER ME SOMETHING. Or discount me. That is just robbery.
So, you at least need a server for the whole work. A pi could do it, although you might not expect stellar performance off of it, but it would get the job done I assume. Except maybe live transcoding if that’s necessary (like watching 4k uhd content on a 720p phone or so).
So min-spec would be the combined min-spec for all services. As they probably also run on linux (i use win-20xx-server) it really should do.
You’d need:
The **nars you’d want (radarr=movies, sonarr=series, bazarr=subs, lidarr=music etc. and there’s even one for porn lol)
a downloader, either usenet (prefered for speed and comfyness) or torrent. So SabNZBd or qtorrent or whatever
If usenet, then you’d need a usenet-account (use one with the highest retention (backlog) like eweka.nl (if you wait for black friday or so, they usually have BIG discounts) and probably an indexer (the search-engine kinda). Like 10 bucks a year if you pay only yearly or like 30 lifetime, depends on service. I’d advise for nzbgeek, they’re cheap and nearly 100% net a result. You could also go for free ones, but they’re always very limited. Probably more than enough for 1-2 movies a week or so. sucks if you want a series with 400 episodes :-)
And of couse:
a media-server. Like Plex or Emby. I personally love emby, i even pay them just because (and for some minor benefits). You could also go for the free jellyfin, but it’s more hassle to setup and i didn’t get it to work reliably (and i’m a fucking pro)
Maybe, if you want to access everything from the outside and don’t want that machine to be totally exposed:
some (reverse)proxy like nginx or caddy. I Prefer caddy, it’s fire&forget like all others mentioned here. Once setup though.
I admit, it’s a bit of tinkering and configuring, but once it’s working it’s fine. The *narrs auto-update reliably, emby does too. Occasionally you might manually update sabnzb and restart emby after an update, but that’s it.
I even integrated everything with telegram so I get notifications when someone added/moved/deleted something or stopped playing or whatever else. completely smart-home-integrated too.
