before me sits a very nervous looking laptop

The reason it is nervous is after i robbed it of its hard drive and replaced it with a smaller one is the next thing is its screen is busted and a good friend wants a computer.

I plan on removing the top bit and binning it but i have been told that taking the cable for the display out gives some laptops serious not happy issues.

model is an IBM 390X

anyne know if i can kill the cable or is it duct tape time
