Opensense is based on BSD, which has a single threaded network stack. This means that low end CPUs can struggle to do >1gbit throughputs. Depending on your WAN this could be an issue.

Sure, but the point of getting a mini-pc is usually not that you have an open case with a second ATX PSU sitting on top to power some extra hardrives.

How will you power the drives?

And from what I have heard, these m2 to SATA adapters have over-heating issues.

You mean “mid” as in midi-tower? Because that sounds like the large version. Well maybe there is an even larger workstation version or so, but the normal medium sized Optiplex comes with one 3.5" SATA bay and one DVD drive.

Optiplex etc. with an Intel 8th gen “T” chips seem to offer the best bang for the buck + energy efficiency on the second hand market right now.

The main issue with these thin clients is the lack of SATA ports and power connections for them if you want to add some larger 2.5” SSD/HDD storage. Usually it is only one, but you can also use the DVD drive slot with an adapter in the mid sized versions.

It’s not a big deal, but a single user instance has some issues with discoverability as it will only show communities you personally have subscribed to.

A fediverse instance obviously.

You can use the same containers with Podman, but docker-compose is not recommended with Podman and you rather use Quadlets which integrate nicely with Systemd.

Previously had some good experience with this store selling refurbished hardware: https://www.computerstoreberlin.de/

Old DDR3 ECC is actually cheaper than regular DDR3 RAM, and it generally works with AMD CPUs (who unlike Intel don’t artificially restrict ECC support to their enterprise offerings).

But tbh, ECC is generally not needed and I wouldn’t bother designing a system around it. Use a file system with checksums and regularly scrub the drives and you should not have any major issues with random bit flips that ECC protects against.

No, typically you use the DNS server of the domain provider.

Hosting your own DNS server is possible, but if you don’t have a static IP address the other DNS servers will have no idea which server to ask when your IP changes, so in this specific scenario it wouldn’t work. And in general it isn’t really worth it as you get a DNS server with your domain included.

DynDNS short for dynamic DNS is what you want. But IPv6 only websites are unfortunately even in 2026 still not accessible by many people due to their ISP only supporting IPv4.

ionos.de has VPS for 1€/month, which are not that bad. Server locations are Spain or Germany afaik.

Because you usually don’t want to do automatic upgrades across major versions. There is a “latest” equivalent for each major version release though.

Install a newer Linux distro on it and run a Luanti server for the kids to play on.

Yes, but afaik the temperature reading is also on the flash itself. On Samsung nvme drives you even get two different temperature readings to differentiate it if I recall correctly.

I ran into similar issues before, but adding a passive cooler brought the temperatures down sufficiently.

However when researching the issue there were several people that claimed that ~70° C is actually the design temperature for these SSDs, which would explain why they usually don’t come with a cooler.

Not too many 8 port managed switches out there with an sfp+ 10gbe port for 50 bucks

Easy to get these days actually, with 10gbit sfp+ and 8x 2.5gbit, managed switches. About $60.

But my actual argument was that your 48 port switch eats electricity like crazy. That aint a cheap switch at all.

But you seem to only need a 8 port at most 🤯

Way too professional looking for this thread.

Also, you got a link to that sticker? Maybe I’ll add that as an ironic reminder to my “Kabelsalat” 😅
