I have used a little Makita cordless screwdriver for the last few years. I highly recommend it for tearing down e-waste. With the right bits this little guy will rip apart anything from a CD player to a server..I have a bigger "drill type"one also. I find myself using the smaller one a lot more than bigger one due to size. It is very handy for getting in small spots. If your interested The model number is td020dsew. They are an impact screwdriver and have plenty of power to tackle any e-waste you throw in front of if!!!
No, I do not work for Makita, I just like there tools. When it brakes, I am buying another one.
Happy Scrapping!!!
