Up until now, I've taken apart all my computers by hand. I tried to use a power drill that I have to unscrew the myriad screw inside desktops and servers but found that it was too heavy and bulky. First, my hand got tired quickly. Second, I had a hard time reaching into corners etc.



Doing it by hand is kind of a pain too. So I am looking for a lightweight power drill that would be close in size and weight to a large screwdriver while having enough battery power to last for a reasonably long time. Actually, I probably don't need a battery-operated one, I can plug it into an AC outlet too, although one with a battery would be more versatile.

Also I would be willing to pay more for a reliable unit instead of getting a cheap piece of junk that will break after 20 screws.

Any recommendations? Thanks!
