There are two reasons why I chose a newer CPU. The first is, that I wanted to future-proof it, that was before I knew of the 13th/14th-gen issues. The second is, that I intend to use this machine for emulation. More specifically PS3-emulation. Because this requires a powerful CPU, I thought newer is better. But I will look, if a 12th generation CPU is enough to get the job done. Which CPU from the 12th gen would you choose?

There are more, but sadly the selection is still very limited. Another issue is that you have to buy dasharo, since there is no coreboot support from a free distro like libreboot, yet.

That is sort of a surprise. Sort of, because I am not yet sure, if I can make it work. It will be part of a later post, but first I need to make sure the internal parts work. The linked articles and videos, suggest buying Intel 13th/14th generation is like playing lottery and the faulty vender bios configurations do not make things easier.

Thank you for this interesting information. I use systemd-boot with secure-boot. I do not know if it has the same issue, but I hope not. If it does, I might consider switching my boot loader or when nmbl is ready ditch it entirely. Like thingsiplay mentioned though, it still might be a good idea to use an iGPU for debugging purposes.

I have seen that. I am currently reading the article linked by thingsiplay. When I am done absorbing the information, I will edit my post and incorporate the information into it.

Thank you for this information. In my research about these chips I have not stumbled upon this issue, since intel seems to be tight lipped about this issue. The seem to blame the high failure rate on the motherboard manufactures and suggest that they are caused by a wrong voltage configuration.
