Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

I have a RPI 4b and 3 lenovos (m93p, m710q, p330).
You can't beat the RPI for power draw (~2w idle and ~7w under max load) but I suspect if you wanted to look at $ to utility measure you'd probably prefer the Lenovo M93P. $50 USD. Mine has i7-4785t, 16GB ddr3 (2x8iirc?) with ethernet, USB etc. Bought 2023/4. I expect base model is still that price now (mines upgraded). The only caveat is that it doesn't have HDMI, it has display port out, but that's just a $5 dongle or SSH issue. M73 would be a touch cheaper.
Iirc the TDP is 35w max and can be lowered / undervolted a touch (don't update the BIOS - it blocks throtlestop).
I turned mine into a retro PC slash game server for the kids (luanti etc). But the siren call of doing truly impossible things with the RPI is too beguiling :)
Eg: running diet pi (headless) with all of my services (media stack, privacy, docs, search, images etc) takes about 300 megabytes (or 650mb if I have to boot into xfce).
300mb, 2-3w.
That shouldn't be possible. I love it.
My next goal is to create an expert system / pseudo llm that sources answers based on user provided markdown or PDF, ZIM files and 4get search or Tavily.
The advantage here is that 1) speed will be stupid fast as no neural network crap (outside of optional extra Markov chain garnish) 2) not stochastic (but allow for llm as optional "plug in module" - pi might actually run a 135M at non glacial speeds) 3) still serves openAI compat endpoint.
Thanks for this, this sounds like where I'm headed. I just hadn't even considered thin clients/mini PCs, and it sounds like a lot of people are using Lenovos for this exact thing. I'm not at the point yet of doing something big, just small home lab, but I would like to get to the point of hosting immich for the family, and maybe having an LLM or SD in there at some point. But by then I'm hoping the RAMpocalypse is easing up. For now, it's just privacy front ends until I know what I'm doing.
Go for it! The m73 is cheap enough (and powerful enough) to run all that and ddr3 is still not insane (say, 2x8gb 1600mhz sodimm if want / need). $100 or so, all up, if you shop around / your local market pending.
Raspberry pi is more elegant / more constrained / more "fuck you, figure it out" but unless you need the challenge, Lenovo is simpler and all around easier first step :). You can't stick a gpu in it (I think the m920 is the oldest one that has pcie - dunno what they go for. The usual combo is something like a 920 and a Quadro P1000 4GB GPU. Maybe ~$300 all up if we're guessing. At which point, there are better, non shoe box options)
