Oh, I don't want this to be a PC. I have plenty of CPU power for what I do, this has a different purpose.

I'm not planning to run anything much on those Celerons - it's mostly just a file server. People do that with a RasPi - a 4-core CPU is going to blow it out of the water I think.

I also wanted some Ryzens, but my requirements were different. I did not want so much computational power, as much as I wanted low power. Combined with the price and availability, this works good enough for mne. We'll see in the long run.

I thought about it, but I got rid of a lot of my electronic junk in the recent years and would have to buy everything from scratch anyway. So I went with the "small and silent and low-power" route. I also think it's going to live in a closet in my home office as well :)

Sure, here's the breakdown:

AsRock J4125-ITX -> 120,62€ Crucial 8GB RAM kit -> 19,90€ 2 x Seagate IronWolf 4TB -> 2 x 114,99€ Samsung 870 EVO SSD 500GB -> 31,41€ (I originally ordered an NVMe one that cost 29€). Fractal Design Node 304 -> 91,89€ PicoPSU -> 35,95€ No-name Power Adapter (220V to 12V) -> 12,99€ Molex-2x Sata -> 9,99€ (there is a ~1€ option, but I wanted a nicer cable for some cable management.

A few cables that I had. Total: 552,73€

I wanted to get a 4-bay NAS, and QNAP, Synology or Asustor would be a bit less, but without the disks. Also, I wanted an x86 CPU, for potential future use. This way I turned out a little cheaper, and it is a bit more flexible.
