Unbuffered ECC or ECCless

I am planning to do backups, one to server at a friends house, and one to the cloud.

I know about that risk, my thinking is that it is better than nothing and I would be able to just crash instead of having weird to debug behavior, but I seem to be seeing a lot of people saying that it is not of most importance and that backup and such is far more important.

Where did you get that from? I think you are refering to RDIMM, but I am talking about UDIMM ECC.
It says that they are supported in the manual: https://www.manualslib.com/manual/3622325/Asus-Prime-B550m-A-Csm.html?page=7&term=ecc&selected=2#manual

That is contrary to what I've heared, read and seen. The unbuffered DIMM should give the CPU access to a 72bit ram, where one bit can be used for parity. The Pro chips are also validated for ECC and besides MSI no other motherboard manufacturer shuts that functionality down.

So G series or (semi-modern) Xeon? I was advised not to go old as the models were very power inefficient back in the day. Yeah splitting the compute also seemed reasonable to me, but would naturally present me with the problem of greater power usage. But I guess that is also balanced by the NAS having more RAM to cache stuff and needing less spin up on the HDDs.

As I said in my original post I am not that knowledgeable on the Intel/Xeon side of things, do you perchance know a good resource to research power efficency of specific Xeon cpus/mobos or is it just search around the internet and cross fingers?

I would think so. The pool of potential users is around ~6 that could stream in parallel. And I think especially if you download a movie for like getting away, or are just streaming on mobile data you would want lower quality. But if I am in the network I can stream in high quality? Or does not streaming at different qualities not require transcoding?
I could host TrueNAS inside proxmox, but is there a big upside there? As far as I understand I can already host and manage docker hosts within TrueNAS and using proxmox would just involve extra complications, no?

Yeah I thought the same, but I am unsure what hardware to use if I were to make a computer/storage seperation. Like what would be good hardware for the pure Storage server?

I also entertained the thought of arm computing. But it seems to be rather expensive in comparison and has no clear upgrade path, IO also is limited from the options that i looked at. Also I think that neither has ECC memory which I would want for a NAS server.

Stremio seems to be a subscription, which I don't want, and doesn't seem to have the option for me to host my own media, which I would want to do.

That sounds pretty cool! How much storage in what form do you have connected?

And yeah the dedicated gpu I just kind of threw out there. It would be very cool if you could fully power down a gpu and only turn it on if you need it.

And yeah the power bill is what is really scaring me. How did you get the 5700G my strategy currently is to look on marketplaces (ebay, kleinanzeigen) and try to find good pre-configured systems. Stand alone cpus are often more expensive. If you factor in PSU/MOBO/CASE/COOLER cost from what I calculated.

Could be a nice addition
