1st off Sorry I hijacked your thread TilDeath
Here is an idea, instead of the the cheesecloth go to http://www.mcmaster.com/#2122k311/=39gu9e and order some of this:
2122K311
Polyester Air Filter Roll Tackified, 1/2" Thick, 8" Wide, 15' Long
$4.97 per Roll
It sounds like you are trying to filter the exhaust air on the inside of your case. I find this to be a bit odd. Any dust particles that get through the filter material should be allowed to leave the case. A simple rack can be made from some sheet metal that can be found at Home Depot. I've been a sheet metal fabricator for 15 years so I can picture it in my head and think each one would take 5 min or less to build and rivet to the case. Cut some 4 x 4 squares out of the material above and it should last a long time.
thanks for your suggestions, but I find Residential to Industrial Polyglass filter media to be too coarse to pick up the fine dust particles that is most comon in computer cases... and using pleated type filter media is way too dense that it affects the airflow performance of the fans making the amp draw go up , power consumption increase and will eventually burn up the fan motors
only reason I thought of possibly covering the outlet fans ( exhaust ) is to keep the fan blades clean on the edges.....
I myself have been in the HVAC industry for over 23 years working from your basic Residential home to doing Casino's and Military bases to Hospitals and "Clean Rooms"......even started out as a full fledged tin binder myself..... until my injurys overtime have moved me out of the field/shop because of the physical limitations.........nowadays I am more computer/software/consultant bound ( for last 12 or 13 years anyhows..... )( well actually I am waiting on my disability to come thru to be honest )
some of what I do for a living:
*Green Building Designation Certifying Agent
*Licensed Energy Rater - Commercial, Government, Public Bldgs, Residential
*HERS Rater & EEM Qualifier

Cheese cloth in 2 layers max will be what I build my filter rack around....... just was curious as to what TilDeath thought, since his line of work is computers......
back in 95 thru 2000 I had the pleasure of building cooling systems for AT&T's plant and redesigning the cooling needs of the DOT traffic camera stations ( was like 46 computers 93 32" Or bigger monitors ) and keeping the equipment room at a constant 68 degrees 365days a year 24/7 for NC ( did 3 of these DOT buildings this way )....... filtering was always an issue, except we built what some might know as " Clean Rooms "
