I also have a monster epyc 7200p, a 1G poe switch, a 56G mellanox optics switch, another server with HBA connected to a DS4246.

Everything I absolutely positively need.

I don't have the old rates, i remember having 60cents or so as the baseline but i don't fully recall.

PETG starts to deform at ~75-85'c. The upper end of that should be fine, but the lower end.. certain things can get close to that temp. So if you've got good airflow, and nothing is passively getting to that temps you're probably good.

The best thing might be a design that has some core that holds the components.. print that in a higher temp filament, and print the outer shells in something a little more aesthetically pleasing.

Also.. remember to check if the filament you're using has any electrical conductivity.
