but I do know that wood+electricity=no good
I hope you aren't basing that off of lightning hitting trees.
Wood won't cause the computer any harm and won't conduct anything. Wood CAN conduct electricity to some degree but it's not going to be a problem for him especially since it's gonna be dry and treated wood.
Plus this isn't the first time wood has been used for a case.
G. Electrical ResistanceWood is a good electrical insulator. However, sig-nificant variations in conductivity do exist. These variations in electrical resistance can be related to variations in grain orientation, temperature, and moisturecontent. The conductivity of wood in the longitudinalaxis is approximately twice that in the radial or tan-gential axes. The electrical conductivity of wood gen-erally doubles for each 10 oC increase in temperature.Generally, variations in conductivity related to wooddensity and species are considered minor.
