Hello!

I attempted self hosting a while ago, but it wasn’t a very smooth experience because I had no wifi, no ssd, no room and no time. I want to get back into it, and I was wondering if I would want to build a new pc. I think it’s a hp compaq 6200 pro Here are the specs: I3 2100 3x4gb ram 250gb +8tb hdd

I would be selfhosting alot of projects, and will try alot of new things constantly, but I definitely want: Jellyfin Immich Password manager Pi-Hole Minecraft server(modded) Qbittorrent

And I’d possibly want: File server(Nextcloud is cool, but it’s a bit too complicated for me) Gitea Code-server Llm Url shortener

Computers here are quite cheap, and I could find an old office desktop with 10th gen intel for about 100€ with relative ease. I could also build it myself, with an old office cpu and motherboard, but that would cost more. What do y’all advise? Can this all be done on a budget setup, excluding the llm? Is upgradeability a problem in office computers?

Thanks in advance!

    I have 3 raspberry PIs, 4 various lenovo tiny PCs all in a kubernetes cluster and it seems I need more RAM than CPU. Storage is on a DIY NAS with 8*8TB disks in a raid 6.

    I run bookstack, nextcloud, 2007scape, gitea, synapse, the *are stack, Plex, and a bunch of other things.

    If I was just starting out I’d grab a used lenovo tiny or two, set up a docker cluster and play with that. There is software to replicate local storage across nodes that I’ve never touched but I’d try out a few of them also if you don’t want to use a NAS. Worst case, just use local storage and the containers will be locked to that host.

    I think Proxmox let’s you run VMs and Containers too if you prefer that route.

        I’ve never actually used swarm so I could be wrong. However, I was under the impression that Docker swarm is a lot easier to use with a lot more examples for people to deploy their Containers.

        With K8s/K3s I find myself translating a lot of docker examples into deployment yamls with Services, Network Policies, PVCs, secrets, etc, etc. It’s just a lot more lines in the .yml files. This also assumes you know that anything that you run in docker you can run in K8s with 1 replica and more is not ideal.

          Ok, k8s is harder but I feel that applying configuration remotely is more robust. I haven’t used swarm though.

      I love those little Lenovo boxes, also recommend.

      Proxmox has also been good for me - great for just quickly spinning something up to play with before committing.

        Yeah, so you have more than one PC and they will talk to each other and decide who hosts what.

        For example, you host nextcloud and the cluster will decide (unless you tell it differently) it goes to PC1. Then you host Minecraft and the cluster will put it on PC2.

        Now, PC2 dies, you unplug it, or generally something bad happens. The cluster will see that Minecraft isn’t running, PC2 is down, and start Minecraft on PC1. The best part, just keep adding cheap computers as you need more compute power. One container (Plex,emby,etc) can not run on two or more computers. If you need to transcoded then you’ll want one with a GPU or a more powerful CPU depending on how many people will use the service.

        This all assumes you’re not using local data. Meaning if the Minecraft save and config files are on PC2 and it dies, starting it on PC1 will either not work or be 100% new. There’s other self hosted software to replicate the data to more than one computer or you can have a NAS of some sort.

        It’s a bit more advanced but a lot of fun if you enjoy that kind of thing. It allows you to work on your stuff with minimal downtime. Of

            Thinking more about it, If you just want to host and not mess around like I do, I would use your current computer, install Docker on it and see how you like it. Host a example website see if you can get it to work, Try a Minecraft server and see if it works… If that’s not for you then you can try VMs with an entire OS. This will be a lot more overhead but it will also work.

            After you know what you like (Docker containers or an entire VM), I’d design what you want to do. Are you going to have a lot of people on your Jellyfin and Minecraft servers? how much RAM, CPU, Storage do they use?

            Once you have that information, Look at prices, Do you want one big PC and will it do everything you want? If you need to buy several, maybe it’s better to get a bunch of small ones?

            If it’s one big PC then you’re done. Get it, install Docker/VM and go.

            If you want to play around or you need to get many PCs, do you want to cluster them so Minecraft server can move to a different PC if that PC fails? then do Swarm or K3s if you’re okay with docker.

            If you need to do small PCs, maybe you install Docker normally on each and manage them separately.

            In the end it’s totally up to you what you do. I use K8s :)
