The link is broken for me. But most automotive enamels are good.
Would that configuration work with a blower card? I'm running a 3900x and I'm a little concerned with everything overheating in such a cramped space. Also I've read that negative pressure will accumulate dust so should I be adding filters?
Yeah, a blower would work better with bottom intake. That depends on how dusty your living space is. I prefer to go filterless and just blow out my rig every few months for what little dust accumulates. Filters in general increase the resistance of the intake, making the fan pull less air in a noisier fashion.
