My project is finally live with its first 3 HDDs.
The components that made it into the reused ATX tower case and PSU are:
- MB: Asus PRIME A320M-K
- CPU: AMD Athlon 200GE
- RAM: 1 x 8 GB DDR4 2666 MHz A-Data
- SSD: 240 GB Kingston UV500 M.2(2280)
The 3 HDDs are:
- 12 TB WD120EMFZ shucked from WD Elements
- 8 TB WD80EMAZ shucked from WD Easystore
- 2 TB WD2003FYYS Enterprise
There is one slot SATA left at the moment. As a next step, I will be looking for a SATA expansion card and mounting adapters to fill the upper compartment with more drives.
Power consumption is around 60W in total. From previous measurements, I know that the 3 drives consume 24-25W. So everything else than the HDDs consumes around 35-40W, which fits my initial plan.
