You DO NOT need it!
First, properly made cases are FARADAY CAGES, correct!?
That means that the chassis is grounded and NO EMF can go to
the inside!
After that, you don’t need to know much more.
Yes, ECC memory would detect, correct and warn about bad
memory, but non-ECC would either warn also, or simply crash,
and that’s where a good hardware person or a clone system
come handy.
All modern operating systems do have internal protection against memory
issues, and ZFS has check-sums as well, so worry more a proper UPS and
shutdown after power loss!
Just go see/read what the ECC “fanboys” say in their defense:
NEVER any specific, proven or even a case where they can truly show
“how a bit flips in RAM”.
That just shows a person that has no idea of how modern Operating Systems
have internal checksums and would detect and crash the application…
But them ignorant, non EE people would have zero come-back when you
explain to them how a faraday cage works …
