Need some pointers for hardware (discuss.tchncs.de)

Hey!

I've decided that it's time to finally get something resembling an actual server for my home setup, and I was hoping you folks could give me some pointers (given the current prices).

My current set up is just my old laptop with 2 external hard drives plugged in - one is the regular portal USB HDD, another is 3.5 HDD plugged via powered enclosure (ZFS and LUKS on both). I want to switch that for something relatively small, but extendable, as I want to add more disk space in the future. I'm selfhosting Plex, Immich and Navidrome, and occasionally some multiplayer games like Valheim. I'm not planning to use Proxmox or TrueNAS/whatever, I mostly just plan to throw Debian on it and spin everything in Docker.

I looked through some guides on https://selfhosting.sh/ and on Reddit, but that just got me more confused, as everyone keeps suggesting Optiplexes and NUCs, but I don't get how to combine that with 20TB+ disk space while ensuring the disks are secure and well powered. Plus my understanding is most of those mini-PC's/refurbished workstations use regular DDR3/4, whereas I was hoping to get ECC.

Should I go DIY route, or is there something I could get as a solid enough base to expand in the future? If DIY is the answer - what mobo/cpu/case should I get? My ideal budget (for everything excluding hard drives and maybe PSU since I have one lying around) is ~500 euros, but if paying a bit more would mean a substantially better deal - then I'd be OK with that. I'm in Berlin, so if you know any good local markets - that'd be great too.

Thanks!

Strong disagree. I ran non-ECC memory on my server and services would unexpectedly crash maybe once per week. Over the span of a year I had two databases get corrupted that cost me a lot of time to fix. I tried swapping sticks but it happened with all of them. I switched to ECC memory and the problems disappeared. I needed more memory anyway and the price delta for ECC was about $100. I didn't have to swap CPUs or anything, AMD desktop CPUs and chipsets support it out of the box. ECC memory is absolutely worth it.
