I recently built a PC using a Corsair 4000D Airflow case, but I'm starting to regret it because it has holes everywhere, and I have a cat, so dust is becoming a big issue. I'm looking for recommendations on cases that can effectively minimize dust while still providing good airflow to prevent overheating when the PC is under load. Just to clarify, I already have an air purifier, change the filters regularly, and keep my space clean, but dust keeps building up!

Honestly, it’s really hard to keep dust out of a PC completely. Even with the best dust filters, enthusiasts usually clean their setups regularly—sometimes even 1-2 times a month! To minimize dust, keep your room clean and regularly groom your cat if you have one. There’s not much else you can do aside from that.

I get that, but I've heard of people running their PCs with no fans in cases like mine, which lets in a ton of air, and that's a bit scary. I don’t want to be cleaning my GPU multiple times a year!
