I am trying to put a filter on my aluminum case. The hole I need to cover is about 5.5 x 7.25 inches. DEMCiflex has a 5 bay filter that would work, but it is $20+ shipped. The shipping is what kills it on their website, so I have looked on various US sites for it. However, I can only find their more standard filters like 120mm, 140mm, duel 120mm, etc. Does anyone know where I can find it in the US to avoid the high shipping charges?
I have also considered buying some filter material and just making my own, but I am not sure how to attach it to my case. I like the idea of using magnets, so I can remove it for cleaning easily. DEMCiflex offers magnetic tape for use with non steel cases, but I assume their tape is the opposite pole of the magnetic side of the filter so it would stick. From the reading I have done on magnetic tap like 3M makes it has both poles to stick to metal better, but it won't stick to itself very well. Does anyone have any experience with this?
I also thought about using some small rare earth magnets. I would glue one at each corner on the inside of the hole. Then put one on each corner of the filter material. They should be strong enough to stick to each other through the aluminum case. But, would they be to strong to use in a computer?
