The drill itself will be of most use to modders and system builders alike. I used it to build a system and was able to use it for every screw in the case. The mainboard went in with ease. I had no problem with the small screws for mounting the floppy or the hard drive. The power supply was a breeze and even the video card and other PCI devices were easy. I found that setting the clutch to 3 was just right for every aspect of the build. - gruntville.com
