I have a dell laptop and it has 8 Gb of ram and 1.80ghz processor DDR3 good graphics card and all that , I was wondering if it is possible to run a Mining rig on it , im getting some bitcoin miners from amazon soon so inform me as best as you can, thanks 
Not recommend laptop for mining, overheat > explode It is hard to get a laptop to "explode". If you push GPU to hard I could see blowing it and a puff of smoke going in air (sadly i know this from when I had GPU rigs running what seems ages ago).
It will effect the laptops life if done alot, and the life will be shorter. And you might find parts that don't last long with a laptop mining.
