Hey, what's wrong with taking an old store bought computer and modding it out. I cut a square 8 by 9 hole in the side of my case, and put a clear lexan plate in place of it. Then put a fan in the lexan. And panted the other side. All my fans glow green. Added more, faster memory, and a graphics card. It went from a stock emachines T2895 to a green glowing XBOX monster.
