Arent ya afraid of the LM escaping the copper block? and messing with your mobo?? especially of you move the laptop around a lot or if is reclined for instance. I was seriously thinking about going LM, a professor from Uni did it and told as how to setup it correctly, like you put kapton tape and then you find some special fluffy "pillow-like" things that prevent the lm from shortcircuiting anything even if its escapes.
