How do YOU propose doing this when most computer "experts" have never used ECC RAM and when it's only available in high end specialist systems that aren't on sale in regular computer stores?

I think my knowledge of the topic is pretty good but I learned from this discussion that almost all AMD CPUs support ECC RAM and you apparently just need a motherboard to match. When accompanying people who were buying "gamer" PCs (after they rejected my recommendation for a second hand workstation grade computer with ECC RAM) I never witnessed store staff saying "hey you could get a motherboard with ECC support".
