Two of the PC's I got from ewaste work. third one doesn't. can't check the lenovo mini pc because it needs a prepriatary cable to power it.

This means I can buy two sata expansion cards and put one each in a box and get like 10+10 sata hdds in them.
I can control them with my server and they can be my little slave boys hauling data.
but it means i need to buy another router to ethernet them.

now i need to check all the hdds one by one to see which ones are good.

One is a ryzen 2600 6 core with 32gbs of ddr4.
the other is a celeron 4 core with 8 gbs of ram.
