Depends how many major cities you want it to power.

Could always look at an atom mobo and cpu and pair it up with a 4350 if you wanted hi def playback.
Or most likely a le-1640 and a 740g mobo.
Could use 1 stick of ram and a compact flash card - serial ata for storage.
Won't be fast, but will do as needed and use very little power.

E5200 and GA-E7AUM-DS2H motherboard actual measurements by me with an Aldi wattmeter thingy on the base unit power supply:

Built-in GeForce 9400 at idle: 41 watts
Built-in GeForce 9400 playing 1080p video: 51 watts.

Gigabyte ATI HD4850 at idle: 80 watts
Gigabyte ATI HD4850 playing 1080p video: 95 watts

Re. the Intel Atom, although the CPU is very low-power, the chipset needs a fan and is quite power-hungry. I can't remember seeing actual power usage measurements, though.
