I dived into the selfhosting rabbit hole once again and again I am stuck at the hardware part. I’d like to start small-ish to make it realisable. I thought about a NAS (Openmediavault probably). First I wanted to do it on a Raspberry Pi with an external hard-drive but then I read USB connected drives are unreliable and so on. Mini PCs are too small to house internal drives so should I go with a (refurbished) business PC from ebay and add some drives to it?But they usually come with Windows 10, which I wouldn’t need but makes them more expensive. I also have at least one old PC case laying around but no mainboard or CPU for it, if that info might be important. Thank you in advance for helping a noob out!

Edit: What I want to achieve: I would like a NAS and (separated) a server with some small services (pi-hole or adguard, syncthing, jellyfin (getting the data from the NAS), and so on). I thought about running the small services with docker on a RPi 4 and the NAS on a refurbished business PC with SATA drives in the case (I checked ebay and there are mainboards with 4 SATA III connectors and PCI so I could even add more SATA connectors). In a second moment a backup server (maybe with borg) would be a good idea but I could also do manual backups with an external USB HDD for the time being.

    Some foundational questions:

    • budget?
    • rough desired capacity?
    • desired level of resiliency?

      Alright, I would like a NAS and (separated) a server with some small services (pi-hole or adguard, syncthing, jellyfin (getting the data from the NAS), and so on). I thought about running the small services with docker on a RPi 4 and the NAS on a refurbished business PC with SATA drives in the case (I checked ebay and there are mainboards with 4 SATA III connectors and PCI so I could even add more SATA connectors). In a second moment a backup server (maybe with borg) would be a good idea but I could also do manual backups with an external USB HDD for the time being. And I have a tight budget.

      This describes what I’d like to do. Budget is low and I don’t have a lot of hardware laying around. For the capacity I don’t know yet but for sure 6tb to start with. I’d like to try RAID (heard a lot, never tried it yet) and another backup (maybe something for the future).

        I would recommend:

        • go on eBay and find some sort of cheap Lenovo/dell/hp thin client for your secondary node. You can find workable 1L-class boxes for around $100. You can get away with some of the older m700/710/900/910 tiny models, but the extensibility of the m720/920 tiny models is going to be much better.
        • for your primary, I think you’d probably be best off finding an old server tower with 8 3.5” bays - if you’re lucky and on-the-ball, you may be able to snipe something like this, but shipping is of course going to be a bitch. An alternative is to pick up another one of those thin clients (making sure it’s a model with USB3, but preferably 3.1 or 3.2 whatever the gen is (side note: fuck anyone involved with the USB versioning scheme, because it’s absolutely indecipherable) that can actually support meaningful data transfer, and then just find a cheap DAS and connect it to that node.

          Thank you very much! Can you elaborate on why m720/920 have a better extensibilty? And what would be a resonable data transfer rate for a DAS?

            They support NVMe and have a PCIE riser; if you get the little adapter from Lenovo’s proprietary slot to standard PCIE, you can run it as a nic, or get an HBA with external SFF-8008 ports and then find a cheap enclosure to use as a custom DAS solution.

          Hello, sorry to bother again but I have a question. Do you think adding a M.2 card with six SATA3 connectors to a Lenovo ThinkCentre M910q would work? I found a M910q for 50 bucks, quite cheap I’d say and the expansion card is around 30 bucks.

            No, for 2 reasons:

            • You will have better luck with a full-fledged PCIE HBA from ebay
            • that won’t fit with how the chassis is designed (at least on the “tiny” model - I’ve no experience with the larger SFF model). It’s on the underside too, so just leaving part of the cover off is not an option.
