I'm not sure this is applicable to computer cases, unless you have some dust-free air source being piped in through a tube out of the window

Sorry, just an opportunity to write about a cool thing I saw in a drama movie/book about a disease outbreak!

Possative pressure casses do exist. I have a silverstone fortress. 2 massive 180mm filterd fans pushing air in and a 120unfilltered fan poshing air out allso holles in the back of the case to regulate pressure. And they stey verry cool and cleen ...

U did a blow job?

Hmm yes I realised last night while in bed (weird what you think about) that I might have been wrong about positive pressure being applicable to computer cases. I guess the "dust-free outside air source" is supplied by the fans drawing air in. Seeing as less air is being sucked out by the extractor fan, positive pressure is maintained, and dust is less likely to get in via other (non-filtered) holes in the case.

My apologies. I wonder how it affects temperature?
