Well, finally went through and airdusted my case and holy hell those meshes work good. Nice coating of dust&hair(we have cats so there is ALWAYS hair floating around) and only small dust particles managed to get into the actual case and a quick spritz got rid of them easy enough.
Now my only problem is getting enough molex adapters or a fan controller to get all those fans hooked up and find some black pantyhose to dust-proof this sucker completely. Still got 3 emtpy spots for fans in it but thinking i'll just throw a filter over them instead of trying to have 7 fans running in this thing(4 is plenty) :\
Damn summer time and cats shedding and dust everywhere. I miss winter
