fit-PC Slim is billed as the "smallest, most energy efficient PC available," and at 13 ounces it just might be. Slim is housed in a 330cc enclosure (4.3 x 3.9 x 1.2 inches), draws a mere 6 watts of power, and like the Linutop 2, runs on a 500MHz AMD Geode. This machine is available in a pared-down 256MB configuration (sans WiFi, hard drive) for $220; a 512MB WiFi version (with no hard drive) for $245; or go all out with the 512MB / WiFi / 60GB hard disk version pre-installed with either Ubuntu or Windows XP Home SP3, for $295 or $335, respectively.
