Subject: How can I build a computer from scratch? No industry made parts.

I want to build a computer with my own to hands no industry parts or 
factory made parts. I know that I might have to have a Black and green 
screen but that is fine with me. I am building the for two reasons: 1.For 
myself, to say I have finally created a piece of actual art and 
technology.  2. I am going to enter it into the Science Fair in hopes of 
winning something and making me a my family proud. Thank You very much. 
Please send me a reply as soon a possible. I also need to know everything 
about it, step by step, right down to the microchip and processors.
