Raspberry Pi Model B
16GB SDHC class 10 card
Model B of the Raspberry Pi features:-
2 x USB 2.0 ports
SD Card slot
10/100 Mbs Ethernet port
I've currently got RasPlex (http://www.rasplex.com/) which is a Plex client for the Pi installed on the SD card but will happily install Raspbmc (XBMC client) if you would prefer that.
It's had little use and has been used to serve up media upstairs, but now a new smart TV allows me to do the same thing, so the Pi isn't required any longer.
Price includes shipping which will be via Collect+
