I feel like this might be easier to dust. Right now if I want to clean my PC I have to open it and hit it with compressed air. This one you can just blow clean whenever.
It's still being exposed to orders of magnitude more dust, which provides more opportunity to destroy components. Increasing the frequency of cleaning also brings with it its own risk of destroying components.
Not necessarily. I mean, it's fully built in the picture and definitely doesn't look like spaghetti. If you cable manage the peripheral cables well I think it'll still look nice.
