Honestly, I never imagined that this kind of exposure could interfere with the human body and potentially lead to illness or health risks. I would really like to understand more about how this might affect the body. What’s the worst that could happen if someone doesn't maintain a safe distance, or someone who never thought about the reason behind his sickness? What kinds of health issues or diseases could it potentially cause?
There are some health-related issues that could arise from having a dozen electronics running 24/7 in the place where you sleep. Most of these problems happen when there's inadequate ventilation in the room, or due to volatile organic compounds emitted from dust burning off hot GPUs or melting plastic.
Depending on the size of your setup, I’d say it's generally safe to host a small rig in your room as long as you keep it dust-free and well-ventilated. Obviously, with a mining rig running in your room, dust can become a serious issue — it’s basically a dust collector, which can be risky if not handled properly. So again, the main points are keeping things dust-free and making sure there's good airflow.
ASICs are a different story. You get the same shit I mentioned above, plus noise pollution. That constant low-frequency hummmmmm from those small fans can really get into your head.
