Based on some videos of people attempting DIY metal extraction from e-waste, no not really. Sure there's valuable metal there, but only thin films of it, and that's before you get to the extraction problem. Sure you can dissolve the metals off the boards with acid, but then you've got a solution of mixed dissolved metals you've got to process back into different pure metals, and deal with all the chemical waste. A gram of copper is ~$0.01 according to a quick search so it's pretty difficult to get any profit.

edit: don't know what the first metal prices site found I was smoking, but accurate prices make the case even more.
