An interesting article. But he may not have thought through one point. He advocates

The first suggestion, when putting together a computer, is to have a well-ventilated case. … a couple of large fans to expel air out of the case. This is an important concept to understand in computer cooling. You do not want fans only bringing in cooler air, as all it will achieve is an incredibly dusty machine (see images below). There must be exhaust as well. Therefore the ideal way to position the fans inside is always to bring in cooler air inside and remove the hot air through exhaust fans to maximize airflow and cooling.

But for ever gram of air he removes by the exhaust fan a gram must come into the case. So he will still get the same amount of dust in the case whether he uses an expel fan or an input fan.

In fact you can put a filter on an input fan so it will not suck in any dust. Putting a filter on an expel fan is pretty pointless.
