I do open my case from time to time to "clean dust". Only that I got fan filters so it doesn't really get that dusty. Enojying the sight of the hardware everytime I'm in there.
Also when a graphics card is newly taken out of its package it DOES smell nice, no matter if it's high-end, low-end or a butt-fugly nvidia quadro, it's still sexy smelly tech to me.

New sneaker smell.
i don't have sense of smell... don't understand that sensation
new stuff always smells good, especially when you've just paid for it with hard earned money
personally i'm a big fan of the new T-shirt smell, but that new component smell is a gooden too
