Quantity   Component name
1 × A Raspberry Pi (revision 2) Model B, or B+ or Pi 2 Model B or Pi 3 or Pi Zero
1 × A Display Monitor & Cable
1 × 5V Power Supply (for Pi) Power Supply (or if you're ambitious tap your display power supply, you'll probably need a switching down regulator to 5v) Remember the Pi likes something that can source up to 2A.
1 × A USB Keyboard and Mouse for setup (if you want something small and semi-permanent, I've had good luck with this: https://www.google.com/search?q=iPazzPort+2.4G+Mini+Wireless+Keyboard I like the one with the mousepad on the side)
1 × USB Wifi or Internet Connection
1 × (optional) One or more DS18B20s for showing the inside temperature
1 × (optional) A string of WS2818 based RGB LEDs for the AmbiLight effect. At 40ma per LED, and 30 or so LEDs you're quickly up to needing an extra 1.2A from the power supply. Size it appropriately. One option is https://learn.adafruit.com/adafruit-neopixel-uberguide/overview)
1 × (optional) TSOP4838 Opto and Fiber Optic Semiconductors and ICs / Other Optoelectronic ICs
1 × (optional) An IR Remote control ( I use this little guy: https://www.google.com/search?q=Mini+Universal+Infrared+IR+TV+Set+Remote+Control+Keychain )
1 × (optional) Push Switch or Switches connected to some GPIO pins (and a ground pin) for flipping pages like the IR remote
