CPU only 1.2GHz so you don't go crazy but it's ARM, no fan, runs on 5V, has 1GB RAM and 1GB onboard MMC HDD. It comes pre-assembled in a very nice metal case and is about the size of two stacked decks of cards. I reinstalled it with Ubuntu and it turned out to be a very functional little network device. The best thing about this board as a network device is that it has 2 Ethernet ports plus WiFi. I use it as a VPN bridge and it fits that role perfectly. 2 USB ports allow you to add storage and an extra device. It doesn't have an HDMI port, so it's not a common Pi board setup, but for networking applications this device is perfect.
