I'm living in South Africa, just a short walk from the beach, and I've had my PC for about a year now. With humidity levels in my area reaching up to 93%, I've heard that this could cause rust or corrosion in my computer components. I want to know how likely that is to happen, especially since I can't afford a dehumidifier right now and my room can't be sealed due to its open concept design. I do have an AC unit, but it's costly to run all the time, and I'm worried about whether a dehumidifier would work well enough in my space since the air tends to be stagnant upstairs. Any advice would be appreciated!

Honestly, I wouldn't stress about it too much. Just be proactive and check your components regularly for any signs of rust or corrosion. If you could manage it, running a dehumidifier would help, but I understand that it's an added expense. Just keep an eye on your setup and you'll be fine!
Have you considered using your AC in dry mode? If it doesn't have that feature, you might want to just ensure there's good airflow in your room. High humidity can fluctuate, and as long as the air is moving, you shouldn't have too much to worry about for your PC. Most of the time, high humidity isn’t constant, so keep that in mind!
But what does RH mean?
Have you thought about placing some silica gel bags inside your PC? They can help absorb some moisture, but remember to keep airflow good too! Just be sure they aren't blocking any fans or vents.
Just try to keep your PC in a cooler environment. The higher the temperature, the easier it is for rust to develop. Make sure to ventilate your space as much as possible!

Also, if I do find corrosion, what's the best way to handle it?
