Nice china based clone of the Raspberry Pi, called Orang Pi (wow would eat an orange pie?). Anyways…Its got alot of extras that I usually buy separately (memory, wifi, power switch, IR) included for roughly $40. Not bad since I could drop $50 easy for less. Just needs a power supply to get up and running. Oh it has a SATA port too…
