I need to keep power usage in mind and don’t want to spend more than 500€ on hardware. Power is roughly 0.35ct/kwh in Germany
I like the small square machines (former NUC). But I don’t have any overview which ones are worth the price.
For data storage I am thinking about a NAS, but it would need at least two HDDs for redundancy, otherwise it’s not better than an external HDD that I have. Also it does have its own power draw, which isn’t insignificant (10w->~300€/10years).
Capabilities of the machine don’t matter too much, I will see what I can do with the hardware I get.
Is there a sweet spot, a device that everyone buys or cheapest brand or best package or whatever?


You’re worried about power draw, know that each server grade 4500 to 5400 rpm HDD draws around 7watts. You can reduce that impact by having a flash drive for your system files (NAS config, logs, apps…) and setting up spin down times so that your HDDs only spin when in use.
