are the fans run for positive or negative pressure?
cos if you positively pressurise the case it'll blow all the spiders out.

There are 4 sucking air in the front and 4 blowing it out the back.
The idea is to cover them in fine mesh and make the rest of it airtight so the spiders can't get in in the first place.

little pricks always find a way in
apparently it helps to imbalance the fans; either a fifth to the intake side, or make the sucking ones spin faster than the exhaust ones. That way all the case seams and gaps get pressurised with air blowing out too, even if the case is supposedly watertight.

OK, thanks for the idea. I'll stick a reducer on the cables of a couple of the exhaust fans.
