Well, thanks for that link but I was wondering what was behind that mesh and now I know. It's not really made for a 120 mm where the 80 mm goes.
I might very well just get the Antec cheap one slk3000b or whatever it's called again. I'd like to put two Coolermaster 42 CFM 120mm fans in there and a Zalman 7000-alcu. That would not be for overclocking. I just want the most quiet comp I can make. I think as long as I have a small 40mm fan on the Zalman NB47J, I should have no problems with overheating.
Seems that Antec case is one of the only ones you can buy that has two 120 mm fans and doesn't come with a power supply. The cheap PSUs they include in cases I'd rather throw out because they're crap. And it's more enviromentally friendly to buy a case with no power supply and add one I want.
