Antec Nine Hundred Question

[VinDSL]

Is it possible to have negative or positive case pressure in a Antec Nine Hundred?

It would be difficult to accomplish positive pressure in a 900 (and similar) due to all the mesh - you'd have to take steps to block most of the extraneous venting. I'd also move the 200mm fan to make it a filtered intake and block off its mounting hole. But you might be able to do it with a 250mm fan or some such. Maybe do it with smaller fans too - depends on the level of noise you are willing to tolerate. But then, a case with all that mesh isn't designed to be all that quiet.

As it ships, it is probably a negative pressure system as little of the air exhausted by the exhaust fans is provided by the intake fan(s). It may not actually be able to generate any level of vacuum within the case because of all the mesh but air and dust will be drawn in thru any available spot.
