Don't know about that. I'll probably clean up the edges the next time I have the case apart. FWIW....the fan is not mounted directly on the case. I used the shells of two old 80mm fans to space the fan further inside the case. Then on the back-side of the fan, I mounted the shroud off a Zalman 5700....

Heh....I can answer that last question about free-flow. I have that fan you see blowing directly on an Alpha heatsink through a shroud. The alpha had no fan during the tests....just the air blowing from the rear fan. I used a constant velosity fan @2400rpm. I measured the cpu temp (internal diode, a...

Gdog....I suppose those Bounce sheets are better than nothing, but we get back to the surface area thing. Simply not enough. If they're effective enough to filter out dust, they'll clog quickly. Then there's the sound factor which I never even mentioned. If you put a filter of any sort right next to...

I've experimented with different filter setups, different types. What I discovered is the standard little foam pad most setups use, is way too restrictive, even for a slow-speed fan. Not to mention it doesn't stop the fine dust that coats everything. I have a very dusty house, mostly due to pets (pa...

If you run the fans fast enough, you'd be right. But with low-speed fans to maintain the quiet, the positive pressure is greatly reduced. Thus I had to seal everything to maintain the pressure. Also, unless you run the computer 24/7, which I don't, dust can get in with the computer just sitting ther...

I wonder if people ever test these devices before they try to sell them? A simple test would prove this thing would raise your computer temperatures to dangerous levels.

Ambient air for CPU cooling?

The coolest air most of us have available for CPU cooling is outside the case. Your case fans blow this air into your computer. Why not take this one step further? Blow the cool air directly on the CPU heatsink by ductwork, a shroud, or some other method. The new Dell computers I've taken apart do j...

You know I too was wondering about the non-removable top and right side on my 2600. But when you look at it closely you see how much more sturdy, solid and less vibration-prone the riveted-together one pice top and side makes the whole case. The setup IMHO greatly adds to the quietness of the case.

Actually beige colored drives go very well with the grey metallic. Since you'll probably be using it with the door closed, I wouldn't mess with changing color.
