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?
I’m pretty happy with both form factor and performance of my Zimablade
Your own calculation is the thing that should pick the machine. At 0.35 EUR/kWh a single watt running around the clock costs roughly 3 EUR a year, so the gap between a 25 W old laptop and an 8 W mini PC is about 50 EUR a year, or 260 EUR over five years. Half your hardware budget, paid in electricity.
That’s also why cheap used enterprise gear tends to be a trap at German prices: low purchase price, 40 W at idle. An N100 or N150 box with 16 GB and an NVMe drive sits around 6 to 10 W idle and fits inside 500 EUR comfortably. On the storage side, two 3.5" disks add something like 8 to 12 W if they never spin down, so spindown is worth configuring when access is bursty, and if your data fits on SSDs the power question mostly goes away.
Thank you you’re right I agree.
