Transmeta Meets Blades
The Griller writes "Gordon Bell, one of the creators of VAX, and Linus Torvalds were at the launch of a new supercomputing platform at the Los Alamos National Laboratory. Based on Crusoe processors from Transmeta and running a version of linux, it is aimed at being cheaper than conventional supercomputers by requiring no cooling and lower maintenance.

The only trick would be getting the things to work properly in a headless configuration -- Apple won't ship them without a graphics card, but I'm relatively certain that you could get a LinuxPPC installation to work even without the card installed.
