This little PC is roughly the size of a paperback book, and consumes a mere 3 to 5 watts of power. The little machine that makes the Mac Mini look bulky by comparison (in size, not power) comes with Linux pre-installed, has a 500 MHz AMD Geode LX800 processor, and is equipped with 256 MB of DDR RAM and up to 512 MB of NAND flash.

Here are the specs:

# 40 GB hard drive
# Dual 100 Mbps Ethernet
# SXGA graphics controller, resolution to 1920 x 1440
# 2 USB 2.0 high speed ports
# Audio in/out interfaces
# RS-232 serial port
# Single 5V power supply
# Dimensions — 4.7 x 4.6 x 1.6 inches (120 x 116 x 40 mm)

While the machine comes with Linux loaded, Windows XP is easily installable via a USB CD-Rom drive. The box will run you a mere $285.
