jackpcVía Microsiervos.com, encuentro este interesante PC del tamaño de un enchufe!!!,...y no le falta de nada:

(Jack PC) The units utilise the latest AMD Au 1550 RISC processors running at either 333 or 500MHz. That's the equivalent of a 800MHz or 1.2GHz x86 desktop processor. They have either 32 or 64MB flash memory to store the operating system (Windows CE .NET 4.2/5) and 64 or 128MB RAM. They can be powered either through a plug on the front or, ideally, using Power over Ethernet (PoE). PoE means the unit is powered over existing structured network cabling from a suitable PoE switch or PoE power injector.
