Wow, did this thread veer off-topic!

This is probably a high estimate, especially for an older, single-cpu 
box.

You can probably get an idea from extrapolating these figures [1]:

RAM:  11.4 kWh and   32   L water for 32 MB chip
CPU:   1.4 kWh and    5.9 L water per square-cm silicon wafer
LCD: 553   kWh and 2394   L water for a 15" monitor

A dragonball CPU (2 dies each .343cm x .343 cm) requires 0.3 kWh and 
1.4L.

The impact of producing a CPU seems low to me, especially when compared
to the RAM. Needs to do some more research ... :)
