Very brave sir! PLA starts to go soft around 50-60c With enough air flow it should not be a problem on the inside. I have not measured every part of my PC case but after a few hours of gaming my PC does pump out a lot of heat to the outside. I am planning to do something similar but at least I will be using PETG and I am currently in love with PETG-CF and love the matt look.Yeah PLA. Not worried about it melting though because if the air temp inside the case is 60 degrees C then something very bad has went wrong. I measured the air temperature coming through the front vent and it was only 30 degrees C after half an hour of running the Cyberpunk 2077 benchmark.
