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?

A few years ago I bought some used Lenovo Xeons on eBay. Xeon E-2276G, 2224G, 2174G.
The 2224G pulls 15 watts streaming 4k videos with Plex. They are available for under $500.
For desktop, any AMD mini PC like a Beelink will work well and many are under $500.
