I am looking to build a new PC and want Coreboot installed. However, all I can find online are vendors selling prebuilt machines with Coreboot, such as System76, in which case I am paying for components I don't need. From what I read online, it sounds like building Coreboot for a modern motherboard is unreasonably hard and not practical. I am looking specifically for a mobo that supports ECC memory, and also not Intel, which further narrows my options. Are there any options out there that fit the bill?

I have a pair of PCs, a NAS, my router, and modem all on the same surge protector, and therefore on the same power outlet. A couple months ago I came home one day to find all of these powered down (they had all been on when I left). After turning my PC on I found my router was having issues and I had no internet access. Eventually got the router working but was left wondering what happened. It seemed like a possible power surge, but as I said everything is on the same surge protector (A Belkin I just bought half a year ago, rated for 2500J and 6kV spike voltage). I never did learn what happened, but ever since then my NAS dies occasionally. It has lasted up to a few weeks of uptime but doesn't really go any longer than that.

When it dies, all fans quit spinning. The ethernet indicator lights on the mobo turn off. The NAS is totally unresponsive, I can't ping it or anything. But the power light on the front is still on. It no longer responds to the power button, even a long press. The only thing I can do is pull the power plug or flip the power switch on the power supply. I suppose this must be either a motherboard issue or PSU issue. The NAS is also new, I just built it in January. But it was fine and had no issues until the day of the... power surge? I'm still not convinced it was actually a power surge because of my surge protection. But multiple computers and my router were affected. Because I don't know what happened I don't know how to prevent this from happening again.

So really I have two questions:

1. Does anyone know how to diagnose my NAS or what needs replaced?
2. Any ideas about what might have happened to cause this in the first place?

EDIT: One important detail I forgot to mention. journalctl logs don't show anything unusual after I restart the NAS. No indication that anything went wrong.
