GeekRoo's Mini-ITX motherboard: The Australian company GeekRoo offers a complete Mini-ITX motherboard. The Pi is stored together with the board (and other accessories) in a box, so that one can speak of a Pi-based computer. Among other things, a 2.5-inch hard disk can be connected, which removes the Pi's memory limitations. There is also a 4-port USB hub, an RS232 interface and an Arduino UNO, which can be used to control an Xbee module (the Xbee module itself is not included in the scope of delivery). With the built-in infrared module, the mini PC can even be controlled remotely, which is useful if you want to use it as a media center, for example. The motherboard is available at www.geekroo.com.
