(Click on the plans a second time to see a higher resolution version.)

The concept for this case was as follows:

Current computer case designs share the interior space among all the components. The disk drive, power supply, CPU, and video card all get the same cooling air.

I was having trouble getting a case that both adequately cooled the components and was very quiet. Part of the problem was that when the components started to warm up, the power supply fan would sense it and would crank up its speed to compensate.

So I wanted to completely separate the power supply from the CPU and video card using baffles on the interior of the case. That would allow me to use lower speeds on the cooling fans for each section, thus quieting things down.

These plans were made in Corel Draw.
