Earlier this year I built something similar, although with more space for hard drives:
I used the following components:
Mainboard | Topton N100 (AliExpress) This is actually a BKHD 1264 NAS | 136,69 € |
RAM | 16 GB Crucial DDR5-4800 (Mindfactory) | 40,78 € |
Case | Jonsbo N2 (???) | 138,83 € |
PSU | 300 W bequiet SFX Power 3 (Mindfactory) | 50,39 € |
M.2 system drives | 2 X 128 GB Patriot P.300 (Mindfactory) | 25,78 € |
392,47 € |
For storage I bought used 4 TB drives from ebay for around 40 € each.
Now the system is running 5 x 4 TB in RAID 6 as well as a 256 SATA SSD I had laying around as cache.
The system is using 25 Watts in idle with those 5 HDDs, 1 SATA SSD and 2 M.2 SSDs.
It’s a bit more you’ve been asking for but this option would offer you more expandability down there road.
Who calls rugby “football”? That’s the first time I hear about that.
