OP needs a proper router that make use of their 3g fiber which will be mostly newer and powerfull and has better wifi. That should be their 1st priority.
Edit: You don't need a 2.5gb ethernet (or better for futur proofing) for every client, but that NAS and Hypervisor could use that bandwith so consider yor options while you are at it.
OpenSUSEway is pattern you can install in opensuse which install an opensuse themed sway/waybar/wofi/greetd and a notification center i cant recall its name. It is what I use on Opensuse Slowroll for a less agressive rolling release.
Thanks foe explaining, I know podman is rootless. My service where running their own non-login users (qbituser for qbitorrent, emby for emby and so own) and I needed to sudo if I want to change anything. It's not a big deal for me so Docker seems easier to use.
I'm containerizing everything, I like to keep my setup simple, no OS containerizing since I will be using a low power minipc (NUC, Hp mini, dell micro or lenovo tiny), I will use proxmox in the VM to get an idea on how it works and because I think the web UI might be easier to use than SSHing to the VM. Later on the new server I will mostly use debain+docker.
I considering containerizing everything, except the OS (I'm not ready for immutable OSes yet). I mentioned Docker because it is what I keep finding guides for and which I think is simpler. How is it compared with Podman (for a beginner in containerizing)
Edit: I will mostly use BTRFS and snapshots, and I would definitely put my containers in a separate subvolume to avoid data loss when rolling back.
Thanks for the V2P not, if containerizing everything turned to be a headache, I will opt for a normal non-containerized setup with the idea of converting my VM to a physical machine
Thanks for the note about tftp. I used to use FTP to transfer file from/to my android phone which got me around ~30MB (local transfer), but abandoned it (due to security reasons) for SSH file transfer which only got me ~8MB for local transfer (my phone probably is slow in decrypting). So, I was thinking of keeping SSH file transfer for remote transfer and use tftp (due to its UDP layer) for local transfer.
If webdav offered reasonable local transfer speed, I will use it to replace all the above.
Your comment made me check that, and yeah, those requirements can be extreme for someone like me who look to use it for two pcs and a phone on a 6th gen intel nuc
Make sure to backup you data beforehand, If you need an application for your work check if it exists on Linux and what alternatives you can use if it does not exists.
I had a gtx1060 when I started using linux, then upgraded to 2060 then again to 2080, they all worked fine without any major problem (except that file system checking at boot sometimes and wayland).
Last year I upgraded to RX6800 and man everything just works, no more filesystem checks at boot, Wayland is mu way to go now.
If I have a nvidia card now I would just use, but if I'm buying a new/used gpu it will definitely be AMD.
Android is no problem at all, Tizen however is a mistake I will never do again.
I have a MU7000 samsung TV (2017 model), it has plex (came free in its store) but no emby (emby is another option that is mostly open source) or jellyfin (Emby fork that is fully open source). I had an Intel NUC5 celeron based that acted as a server, the cpu was pretty efficient (6w) but it was not powerful enough for transcoding (converting the video to something the tv can play)
My experience with my Samsung TV.
Plex: Can direct play almost anything (stream to the tv without converting the video). I'm a non-native english japanese anime fan who needs subtitles all the time. The problem is that plex will turn to transcoding if subtitles are on and my server was not powerful enough to handle fluent transcoded stream.
Emby: it is not in the tizen store (at least for my tv), fortunately the emby team release a tizen binary that can be installed through a USB thumb drive. Now emby works pretty good with and withouth subtitles. It does not have ads (for premium subscription) on android but it does have a once every 24h add in the Tizen version. Not a big deal but just remember you are more likely to be treaded a 2nd class consumer for having a damn Tizen TV.
Jellyfin: Not available on Samsung store, I had to enable devlopper mod on my tv and install Tizen studio with CLI on my pc to compile Jellyfin for my TV, then install it through Tizen CLI only to be surprised by how sluggish it worked, the UI was very unoptimized which is natural as it was not supporting my tv to begin with. Half my remote (samsung one remote black version) did not work so I decided it was not worth it.
