Thank you robbee for your know-how.

I myself am intrigued by your experience in 3D-printed cases.

 I used "Extrudr PLA NX-2" for my previous Prototype.

After disassembly, I couldn’t find any warped parts after 1 months of extensive CPU&GPU rendering tasks, mainly fluid simulation work.

Average 79 C CPU temp(3900x 240mm AIO)

GPU has a blower-style cooler, heat will be evacuated immediately

Second prototype will be made out of ASA, with the thought of a longer lifespan.

I will revise my last statement of the material recommendation of PLA:

• PLA suffices in terms of thermal stability as Radiators mostly don’t reach temperatures higher than 60 C
  • on the note of Filament-quality, pls mind the cheaper ones and go for suppliers that offer datasheets of material properties, where thermal resistance is higher than 45C
  • expected lifespan +5 years (without constant UV stress; e.g. Sun)
• PLA will warp after extensive Hardware usage, resulting in warped parts
  • negative case pressure recommended
  • use at your own discretion
  • expected lifespan +2 months
