If anybody is interested: an old workstation/server costs about 100€, a 2TB external Hdd 50€, that's about all you need to self-host your Netflix.
to proceed flash a Linux distro of your choice (I recommend Debian 12 stable) follow a tutorial on YT on how to install it, it's very simple.
Download and configure jellyfin. Open the 8096/8099 port on your router.
If you live in a country where downloading "Linux ISOs" is frowned upon, be sure to use a VPN while downloading the latest Linux Mint release for your jellyfin server.
Load those fancy new kali Linux live CDs on your jellyfin servers, download clients for all your devices and enjoy!
Guides for everything I said can be found online, expecially on YouTube.
Just to add: jellyfin is free and open source: you know it does not spy on you and it does not build a profile on you to then sell your data to ad companies, a huge plus if you ask me.
The package manag- oh it's windows right
