I used PETG to print it, which should support the heat without problems. I also added two fans behind, so that the disks and enclosure stays cold. For now, I only have 4 drives in it, and it does not move at all and holds perfectly fine.

Just to add to this, I would personally use ABS/ASA, or a fibre variant of those, like Carbon or Glass (if you don't have an enclosed printer). PA (like PA612) is also a good option. Basically anything that can handle higher temps.

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.

Yes, I would have loved to use a 'better' material, but my printer is not enclosed and I'm not sure it can print CF filaments (I think I would need to change the hot end at least). But soon I will hopefully get my hands on a new BambuLab printer which should let me play with those materials!

Actually you can. You'd need a hardened steel nozzle and that's about it. CF/GF filaments are designed to be easier to print, even on an open printer. It's almost the main reason they're popular.
