OP, what parts did you order and from where. I am thinking of building one for the upstairs old analog TV.
I went to this site
www.buyapi.ca and this is what I think I need
Raspberry Pi Model B × 1
Raspberry Pi Enclosure Black × 1
Micro USB Raspberry Pi Power Supply 5.25v 1500mA /w micro-USB cable × 1
Miniature WiFi USB Module for Raspberry Pi × 1
XBMC (OpenELEC) SD Card 8 GB Class 10 × 1
IR Wireless Remote Control Kit with Receiver Module × 1
FLIRC RPi USB XBMC IR Remote Receiver × 1
Any suggestions?
