UltraLowPowerHomeServer

Hi All

Currently my home server is a Pi and a external hard drive which is good, however i find myself missing a Gigabit Ethernet port, i also use the linux program motion to monitor a HD security camera which utilizes a large portion of the cpu.

what would be the best hardware to replace this given the following requirements.

 - 1 or more Gigabit Ethernet

 - 1 or more USB ports

- total average power consumption of <30watts including hard-drive

- 1 tb of storage could use old hard drive

- at least 512MbB of ram

- cost <$200

Live in Australia so amazon is a non starter.
