Does this have the ATX12 connector on it, and does the motherboard need that kind?

According to the presentation, which is linked somewhere on there, it is supposed to be 35db (or something) at normal operation. I thought it was quite odd at first to have so many fans, but then noticed that the top version is supposedly faster than a dual Xeon system.

It would be nice if AGP cards could be flipped upside down somehow- its much more convenient for cooling by exhausts, better for ducting, you can have larger cooilng solutions... but then again, it could also get in the way of the NB and CPU.

You will very likely have to vent the closet, otherwise the heat will just build up, unless the walls can somehow absorb and remove the heat. The simplest thing would be to put a small vent at the top part of the door. You would have to cut some opening. And even better, put the same venting at the ...

I'm not sure what you would fit in there if you didn't get the motherboard. Not clear if it is custom or not, but the harddrive and cd plug into the motherboard on a special board.

Have you adjusted the recording input level for the soundcard? The reason I point this out is that seems to be independent of any controls in the AIW software. You have to adjust it yourself to an optimum level.

Hey if you want the 300watt version of this power supply (FSP300-60PN) with a nice case that has a lot of cooling options for not too much money, check this out: http://www.directron.com/3051lb3a.html Unfortunately that case is not that appealing to me.

What I think you'll want is to elevate at least 1 inch from the ground. I think you would want the exhaust from the box to not be inline with the exhaust from the PC. This will help with stopping the PC noise from escaping since you remove the direct route for the noise. This white melamine people h...

That's a thing you see, if you invert the motherboard and have the CPU at the bottom and the inlet of the case directly in front of the CPU not blocked by air you can have the air leave behind the CPU. Also you're AGP card is with heatsink pointing up, not down.

You could always turn your case upside down.

But actually what you're talking about is having intake go straight into the PS and exit. The intake would be some vents in the case and only supply air to the PS so the air would be cool air.
