Rubik's cube sized PC

I have seen tiny sized pc but the Space Cube tops them all. Its dimension is 52mm x 52mm x 55mm, very close to the size of a rubik's cube, smaller than the size of my palm. Its Compact Flash Card allows the installation of the Redhat Linux as its operating system aside from its built in 16MB internal space. Processor speed is clocked at 300MHz maximum with an 16MB DDRSDRAM memory. The space cube include a USB port which maybe used to attach a hub for keyboard and mouse installation and other USB 1.1 enabled devices. A DB15 port for display, a RS232 port and an Ethernet port for network access. It also has a built in phone jack, Speaker out and Mic in for audio. This is obviously a desktop pc that could be used mobile aside from a laptop. Its price is around $300, not bad for a portable computer. This pc is very good for my interfacing experiments which would allow me to do testing outdoors. More info about the space cube on their website at the maker homepage Shimafuji Electric Incorporated.
