If reduced to it's component compounds the boards and screen would 
generate quite a bit of silicate (pure silicon in the case of the ICs 
and circuit boards). Glass is silicon dioxide don't forget.... As for 
the lead I don't know what proportion it is used in it CRT screens but 
I'd hazard a guess at 'not enough' in the case of 1980s CRT screens! By 
mass I still think silicon would win hands down though, but the lead 
would make it a bit risky ;).
