I live in a dusty climate so, like you, I had also decided to go with a postive pressure case before seeing the Silverstone article. About that article... I noticed the top fan in the diagram in the article is being used as an intake fan. Wouldn't that blow hot air away from the exhaust fan on the back? I'm slowly prepping an Antec Two Hundred V2 case for positive pressure. I chose that case because it has a front dust filter that is fairly easy to access for cleaning (and vacuum between cleanings), has room for six 3.5" HDDs and an SSD, a 2.5" hot swap bay (I'm adding a 3.5" hot swap bay as well), isn't too huge, and didn't have a side panel window or glaring LEDs (I know, that's sacrilegious but I'm an old lady). It has (or, rather, had) a 140mm two speed top fan (I'm ditching it and blocking off the opening, using a dust filter housing that has the filter medium replaced with a solid panel so it won't look Mickey Mouse) and a 120mm two speed rear exhaust fan which I'm replacing with a Thermaltake AF0018 variable speed fan (it has a little pot attached for controlling the speed; handy since there really isn't anywhere to put a fan controller since I'm filling all three of the 5.25" bays); these fans are reasonably quiet yet still put out a fair amount of air. I'm also installing two of the Thermaltakes in front of the HDDs, which will pull air through the front filter and push it over the HDDs, and another of the Thermaltakes on the left side panel. The PSU is a modular Corsair HX750w. It's a bit oversized but that will let it run cooler which will keep the case cooler and reduce the speed of its fan so it doesn't suck as much air from the case and make as much racket. I'm sealing as many of the holes and crevices as I can and making custom power cables instead of the ridiculous modular ribbon cables that came with the PSU to reduce air resistance (making the cables is tricky and TEDIOUS! since I'm working in tight quarters). I had thought about keeping the top fan (although I would've reduced it to a 120mm) and blocking the back fan opening instead so there wouldn't be an air pocket until I noticed the bottom face of the top fan is even with the top edge of the back fan so the air pocket would still be there anyway so I decided to keep the back fan since that was easier than keeping the top fan. I had thought about making the top fan an intake fan but, as I mentioned earlier, I had concerns about it disrupting proper airflow. I won't be overclocking this computer since I'm not a gamer and don't have the need for speed (except when booting up; running a SATA 3 SSD boot drive will be fast enough, even if using only an i3 or i5 CPU) so it shouldn't be too hard to cool, even using a stock CPU cooler (I'll need one or two low power graphics cards because I'll want to run three monitors and two TVs; both TVs can be fed from a single port through a splitter). Anyone have any thoughts on this?
