I gutted the brand new 300W power supply except for cooling fan, power switch and power plug. The 3 1/2" form factor board fit perfectly. The gold anodized aluminum heat sinks are one piece, which actually covers the three main chips.

Power supply cases really do make the perfect mini-computer case. The Advantech 5820 babyboard sports a "passively" cooled Geode 233MHz processor. It's hardly passive with that monster fan running. I liked the idea of recycling the power plug and switch too.

Pictured is the faux wiring harness, an integral part of the deception. This completes the lower section of the piece.

The hardest part of the project was finding this. I researched and priced out tiny industrial power supplies without any reasonable conclusion. Then it hit me. I ripped apart my external CD burner enclosure and found this little jewel. Perfect. It has two fan connectors and the 4-pin Molex connector required by the board.

Power supply and USB header installed into the top section.
