I had one of these wind tunnels for a while in the 2000s. A dual 1.8ghz model. It looked ultra-cool, beautifully designed inside and out. But it ran really loud even by the standards back then... There was actually a high end water-cooled model that was notorious for developing leaks - doubt there's many of those remaining in service these days!
