What you are describing sounds like plain old debian. Stable thing that you can occasionnally update, perfect for all your server stuff. All my servers run CLI debian (probably won’t be your case as you mentionned some gaming on it too) and I tend to forget about updating them (or even having them to be honnest) due to how stable the damn thing is.

I would definitely give Bazzite a try. If you are looking for stability and a set and forget OS. If you don’t like it you could always try something else.

If you are looking for something to tinker with and change things like manually changing packages or messing with services you probably want a more traditional “non-atomic” os

Don’t let talk of the filesystem being “read only” scare you. You can still save files to your desktop and documents and stuff in your user folder.

In windows terms it’s more like imagine C:/windows being read-only so you can’t break your system. You can still write files to other parts of the drive, but it prevents you from messing up your install (some people like this added layer or stability, some don’t like it because it makes tinkering with your system harder)

An atomic OS is kinda like a phone OS, in the sense that every version of iOS 26 comes with the same version of Safari and the same libraries. It makes it so any bugs are reproducible and easier for the developers to track down. Packages are pinned to the OS version. (For example all installs of Bazzite 20260101 will include Nvidia drivers 590.44.01-1)

In a more traditional Linux distro because packages can be updated to whatever version if you install Ubuntu the version of Nvidia drivers is not tied to the OS version. You could have an install of Ubuntu 25.10 and could have a completely different Nvidia driver version from someone else on Ubuntu 25.10. This could make bugs harder to trace because you could have the same OS version but different packages. Think of this like even though you and a friend could both have (Windows 11 25H2 installed you could have different drivers installed)

As for updating Bazzite generally auto updates once a week in the background. It requires 0 manual intervention and keeps your packages and drivers up to date. You can turn this off if you wanted to. Since it uses a “image” based approach (again imagine upgrading from iOS 26 -> 26.1) it is able to save the previous version of the OS. So if the upgrade broke something you can roll your system back to a known good state with a single command.

If you are looking for something that’s set and forget I would definitely give it a try.

If you want to tinker with it and figure out how Linux works I would probably try arch or something

You won’t just replace Windows with Linux. You’ll transition.

It takes some time, but it’s not that hard and it pays in the end.

I’d likely update it a few times a year, knowing me.

I think this needs to be clarified… I dont know anything that isn’t going to be getting security updates fairly regularly, which you’re going to want if its hooked up to the internet. Do you mean you don’t want to have to reboot often? Because that’s more doable, but bazzite is a bad choice for that, it can’t apply an update unless it reboots because of the immutable file system. Also cachyos is arch based so you’d likely be wanting to run updates around weekly.

I’ve heard that Bazzite can be a little more locked down

No this is generally put out there by people that don’t understand the workflow of an atomic distro. Yes the file system directories are generally readonly. You can still layer packages, or use flatpaks and sysexts to add software or install things in a container. There is nothing much that can’t be achieved in an atomic/immutable distro, its just a different workflow. If you want something unbreakable an atomic distro is the way to go

Check out Nobara. It is based on Fedora, comes out of the box with everything Bazzite has for gaming (Steam, gamepad/joystick support, etc…) but is not an immutable distro and not as heavily locked down.

I’ve been a Windows systems admin professionally for 20+ years and although I’ve managed a few Linux systems professionally, at home I’ve mainly used Debian for tinkering, running Docker, and dedicated servers for me and my friends. My personal PCs have always been Windows based.

I really wanted to use a Debian based distro, because its what I have most familiarity with, but there just isn’t one that isn’t Ubuntu based or updated frequently enough for the gaming I like to do. I’m sticking to Deb for my servers. Fedora is just as mature and reliable, and gives me the degree of control I want over system config without being cumbersome. I have some pretty specific network config and software requirements that necessitated some tinkering in /etc and .conf files that Bazzite was not going to let me do.

I also wanted a PC that just worked, minimal tinkering. I do not want to spend my gaming time trying to troubleshoot obscure Linux issues. My personal PC use is like 80% gaming. I have a good virtual infra home lab setup. A Synology NAS that holds my music/movies/file archives.

Nobara setup was a snap. Ditto installing Discord. Both webcam and headset were auto detected. I installed a few flatpak apps including VLC, Putty, Firefox (preferred browser). VLC was able to stream video/audio from my NAS without any additional changes.

Fired up Steam, installed Elite Dangerous, plugged in a T16000 HOTAS joystick and done. Was playing that same night. Ditto any games using my Xbone gamepad.

The only fishing I have had to do online for remedies and workarounds have been related to some small 3rd party apps I use to support games like Elite Dangerous. Most additional software I’ve installed via Flatpak, which is amazing. However, by design flatpak apps run in sandboxed environments and are not given full/free access to the file system. (this is a great thing). I’ve added Flatseal to give me a GUI for modifying flatpak app permissions when needed. (Discord, for example, needed additional permissions to allow me to copy/paste screenshots/pics into chat)

I created a separate partition for installed games. Most guides offering help on installed games assume games/apps are installed or looking in your /home folder, but for me it was on a separate volume, which required permissions tweaking or just looking in a different path.

I cut over during the holiday break. Overall, the transition has been seamless and painless.

Given your requirements, absolutely I’d also recommend against Bazzite and CachyOS, at least today.

Debian stable. Enable security updates by unattended-upgrades and you can basically go over a year without manually updating (aside from the occasional reboot to activate the newer kernel).

Then if you’re not already into containers, I propose learning about rootless Podman and using that to run your arr stack services. For example using docker-compose and/or systemd services.

If you don’t mind going a little bit more of the beaten track, then I also encourage you to check out Alpine Linux. Their wiki explains how to install it with a read-only root filesystem which it sounds like you’d like. But since it’s early and a commitment, maybe save this adventure for later.

Arch has a like 10x more update churn than Debian or sth and is not stable in the same sense.

For a more hands-on system, or something offline, Arch is still great.

Do you know about piping? It changed everything for me back then. People do the weirdest complicated things that are mostly a few piped commands. One command if you master awk 🤣 but let’s not go there.

Just make a partition and install a distro: Try Bazzite(fedora); don’t like it? Try Garuda(arch).

I just use fedora and install the stuff myself, which is probably similar to how Windows works since there’s no “windows with steam and Nvidia drivers”

Don’t use Debian on the gaming PC(or any “stable” or “lts” distro), everything will be out of date and Gaming on Linux typically needs the latest packages.

The big thing you probably will care about is the Desktop Environment; which is what you’ll actually see when using the PC. There’s Gnome, KDE and more, each distro will typically let you use pic which one to use.

I have neither used Bazzite nor CachyOS. You’re sure you don’t want to try Linux Mint? It’s extremely stable Linux for your grandma. Seriously, my dad’s laptops run Mint, and have for the last 5-6 years. When he gets a new laptop, I go over and install Mint for him (and he doesn’t know what Linux even means, he keeps calling LibreOffice “linux”). He asks me for help with his Windows desktop all the time (which he needs for certain software), but linux “just works” (his words). My son’s gaming computer and our house TV (which is an oldish Dell All-In-One that both my son and my wife need to be able to use) also run Mint.

For me, work computers that need to be stable run Mint, work computers that need to be secure run Qubes and servers run Debian.

Okay, aside from all the distro advice, I have some practical install advice.

There’s a program called Ventoy. At ventoy.net

Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With Ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly. You can copy many files at a time and Ventoy will give you a boot menu to select them

Most distros these days have a live CD option, meaning you can run the distro and test how it feels without actually committing to an install.

So, take all the distro options here and throw them all on a thumb drive with ventoy installed, then you can simply boot into each one.

Now, my personal fav distro is called Garuda. It excells at gaming, and can do everything you want, but will put a red blinking icon in the task bar if you don’t update every week or so.

Garuda is Arch based.

I don’t mind tinkering, but for this PC, stability is key

I don’t want an upkeep heavy OS

Yeah I wouldn’t recommend a rolling release distro like cachy then lol. Debian or it’s derivatives would be better for something low maintenance that you don’t need to update frequently

I also wouldn’t recommend bazzite, just cause im not a fan of immutable distros as they feel too locked down for me, but I’ve never attempted to set up a jellyfin on one, so someone else with more experience would provide a more concrete answer for your purposes there

Debian. It’s rock solid. You don’t need anything flashy or new fangled if you’re just building a home server.

I wouldn’t suggest bazzite or cachyos for a newbie.

Bazzite is good for gaming and general computing. If you want to run servers or tinker with the OS at all it becomes annoying and impractical.

Fedora is stable, with modern packages, and is what Bazzite is based off of. I’d probably recommend that.

Debian is rock-solid stable, but lacks newer packages. It’s great for a server, not so great for gaming and general computing.

If you game, Bazzite with KDE is damn near perfect. I’ve been running it for a year and never had a problem making it do what I want it to do.

I don’t want an upkeep heavy OS.

Bazzite is immutable, updates are easy and not bothersome, and if for any reason one ever breaks something, a single command (sudo rpm-ostree rollback), you go back to the previous state, easy peasy.
