Yeah, an SSD-only NAS would be the dream, but as I mentioned in another comment, it’s out of my budget, one 4TB SSD costs as much as two HDDs :(

Thanks! Yes, I’ve considered second-hand hardware, especially mini PCs like the one you linked, for their low power consumption. The issue for me is that they typically only have one SATA port and no space for 3.5" HDDs (only 2.5"). As you mentioned, I could probably take the board out of the case, but can it be mounted in a standard ATX case? The board layout doesn’t seem to follow standard dimensions…

In fact, I already have a mini PC (an MSI Cubi 2 with an i3-7100) that I sometimes use. I’m sure it’s fairly power-efficient, but again, it only has room for one 2.5" HDD, which limits its usefulness for a NAS setup :(

Another concern I have with second-hand hardware is what happens if something breaks. Is there any warranty? With new hardware, I can simply send it back and get a replacement, which gives me more peace of mind.

Thank you! Yeah, the R1 is very tempting, but 14W with the HDDs spun down is a little higher than I’d ideally like. Still, it’s reassuring to hear that it’s been reliable for you.

By the way, can you tell me more about the mini UPS you mentioned? It sounds like a great addition, especially for providing backup power to both my router and the NAS.

Thank you! When I set up the server with the old netbook I mentioned in the post, it was mainly because of the built-in UPS, which was very convenient.

However, the main issue with laptops is that they typically only support one drive at most. I know it’s possible to hack something together with splitters or external boards, but I’m not a fan of relying on a hacky solution for something like this. Plus, the server will be placed in a visible area of my house, so I need to consider aesthetics as well and go with something that looks at least somewhat nice.
