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.
