No, I wrote this a bit confusingly. There a lot of these mini PCs with the same form factor as thin clients but much beefier specs. And some of these are actually build to handle AI workloads and could be a good choice if your homeserver should run such tasks. But other than that they just draw to much power. Actual thin clients usually have similar or less cpu performance than a N100 selfbuild but if you ever feel like you need more power there is no way to upgrade it but get a completely new thin client. Plus the self build will be more reliable because of the SATA connections and often has better networking.

If you want to use a thinclients only a few have that little power draw I would even consider to the heart of my always-on homeserver/NAS (so pretty much only Intel NXX processor builds). There a plenty of ITX and mITX mainboard + N100 combos out there, paired with a decent NAS case you are running a cheap and expandable config. And you can easily run a lot of docker containers on there with enough RAM provided, because normally you are using only a few services at a time and for that a N100 is plenty. I would only consider those thinclients if AI is something you are planning to run.

They are the only ones supporting several hardware based security features.

Only Google Phones are compatible with gOS. I'd recommend getting a different phone the next time. Xiaomi is a shitty company doing their best at sourcing their resources for the hardware the worst way possible. And they are a privacy nightmare.

You don't have host your whole infrastructure on AWS to be affected by this. Even if you use one of their services it can break the whole site. And depending on what of their services you use Amazon won't necessarily be able to connect tge dots.
