This is the smallest linux computer I have seen so far. The Picotux Linux Computer is just about the size of an RJ45 connector and is powered by an 32-bit ARM 7 Netsilicon NS7520. More of this tiny marvel here . Source: picotux.com Related Post: Aleutia Ultra Compact PC

Measuring only 11.5 cm, the Aleutia E3 PC is the smallest PC I have ever seen. This green PC is powered by a MSTI PDX-600 1.0GHZ processor and runs on Ubuntu and OpenOffice. It has no moving parts as it uses a compact flash card as the storage device instead of a spinning hard drive.Uses only about 5 watts of powerthe same as an ordinary light bulb. This is as green as you can get. Solar panel optional! Source: Aleutia.com
