Believe it or not, this system is from a smoke-free environment and it's not particularly dusty either. Well, it doesn't look like a dusty environment anyway. Yep, leagues away from other systems posted around the Internet that have carpets of dust on them but this just really surprised me, considering it's only been a few months since it was last cleaned. Looking at the IO panel I decided that it would be a capital idea to clean this thing. Just look at those rubber covers! They're supposed to have gaps in them. Considering the state of the rest of this area, I'm amazed that one of the VGA ports isn't completely caked in dust (top-right from this angle, the other three ports were occupied). Similarly, the PSU appeared to get off scott-free. What a state! This case stands upright, yet that's how bad the side panel is. The front vent. Poor thing. You'd never believe the state of the inside. Spoiler See? Told you you'd never believe it. However, this is quite deceiving... I think that a spider decided to make this its home at one point. Evidently, even a spider can choke to death (I never did find one in there). Can you believe the state of that motherboard, considering the state of the PSU? Look at the previous pictures then look at the CPU fan. It's a lot cleaner than I would have expected. Please, someone explain how the RAM is clean!!! More "artwork". Luckily for the spider it's not a gaming PC so the GPUs don't really get hot. I really don't understand how these can be that clean. The whole system is absolutely caked in dust, yet the motherboard dodged it all. Maybe Gigabyte used some dust repellent spray? Yup, this really is before I started cleaning. Front filter, as expected. These 5.25" bay covers have seen better days. Needless to say, I cleaned it all. All looks pretty good but I didn't go nuts with cleaning; I just blasted the system with a compressed air generator.
