AMD has been open source since late 2017?

I use Alpine Linux for all my dockers, small and fast.

Ah they sold boards with the bugged versions of the i225? Mine had the rev3 chip which is supposed to have fixed the issues with the older revisions.

I have a b650e-i

That’s not good, I actively try to avoid realtek cards since they are unreliable in linux. I have an asus board with an Intel nic but I haven’t had these issues.

2.5" disks are SMR, you don’t want that in a raid.

Unless you have use case for that much horsepower I would suggest, like others here, buy a mini PC as a start and if you need more down the line buy a second one. They are cheap, fairly quiet and don’t use much power.

It’s called power supply idle control, worth a test.

There is an issue with ryzen and certain PSUs that when it goes to idle it pulls so little power that the psu thinks it’s off and kills the power, it can appear as a hang. there should be an option in the bios to change it to “typical power” or named something similar.

Yes it’s normal, I sometimes use that to disinfect my ears after diving and it sizzles a bit.

If I where you I would just buy a regular case that can fit a decent amount of HDDs like a fractal define 7 or one of its older versions and transplant your current computer into that with some new drives. 100tb is 5 20tb drives so you don’t need that many.

USB enclosures are not a great way to handle storage as USB tends to be unreliable.
