Using the case as a heatsink

Jozef writes: 'I think liquid cooling may make it in high performance machines very soon. I have this vision of a computer case that itself is used to radiate the heat, and a computer with no fans, just a pump, and the waterblocks attached to all heat-generating components - CPU, chipset, graphics card, power supply. The case could then be actually sealed."

This has been done with several machines that I can think of. I have a "GRiD" laptop, the exotic one with the magnesium case from circa 1982-84, that uses just this approach: all of the high-wattage chips, including the 8086, 8087, and the bubble memory, are heat-sinked to the magnesium case. And, yes, the case gets _very_ warm. (I bought this GRiD for about $175 at Weird Stuff Warehouse some years ago. Not much use except as a museum piece. Last I tried to turn it on, it DID boot up. Doesn't even run DOS, though.)

The Apple Cube also has no fans. The case is the heat sink, convectively cooled.

Jozef,

I remember seeing an FFT processor for airborne aperture synthesis radar about 20 years ago. It had connectors for power, signals and water in and out.
