Hello, all. I've been toying with the idea of putting a blowhole in the top of my Digital Audio case. I've got a Sonnet fanless 1.4 upgrade, a Radeon 9700, 2 hard drives, and 3 PCI cards, so it literally gets hot enough to bake bread in there. The machine is old, and I want to let it breathe! Anyone here had any experience with this, or know of a site that discusses it? Would it be better to exhaust, or intake from the top in this case? Thanks.
