A computer for education

Hi, my name is faizan, i am a high school student that needs some extra money to start a project that can change my future as a computer engineer. With the money that I receive from all of you generous and kind harted people out there I will not be buying a computer but insted I will be makeing one that will impress the people that think I can not make it. Big part of this project is to find out how a computer works and a small part (0.01%) of it is done to prove the people who think I that I will not be able to do this. I have set the Goal to $2000.00 because really do not know how much money I will spend on this project. If I receive extra money i will be donating it to a good cause. One of the causes I will be donating towards is the genocide in Sudan. I have told my parents about this and they like the idea of me doing this but they have told me that I am old enough to earn my own money and to do anything I want with that. This is going to be a fun and vary educational project and i look forward to finishing this before this summer.  Thank you in advance,   Faizan
