It's either bad luck, bad power quality from the mains, or something in the air in that particular area. I know plenty of people running AM5 builds, have done so myself for the last couple of years, and there were no problems with any of them apart from the usual amdgpu bugs in latest kernels (which are "normal" since I'm running mainline kernels — it's easy to solve by just sticking to lts, and it has seemingly improved anyway since 6.15).

I have a really specific Xorg config with my own kernel boot line in GRUB for amdgpu, it seems to work for me. I have not experienced any bugs with amdgpu so far. The GPU and HDD / SSD would stay anyway, I would only have to get everything else.
