Oh god what electrical school did ya go to *LOL* Electrical tape is nasty and horrible and always leaves a mess. If you need to cove the ends of wires you use heat shrink!!!! Here in arizona if I ever cought one of my installers useing electrical tape on anything they would get fired *LOL* Guess it would be ok in a pc case but heating it to stick to wires just makes a god awfull mess if you ever wanna take it apart!!!
