Here's the story: My 6-year-old son and I built this in 2003, using an HP Pavilion. It took about a month and $80 in bricks. There are no screws or glue — everything is held together with Lego bricks. By the way, I saw some comments about heat, but it's not a problem. This thing stays on 24/7, mostly as an email machine, and the windows above the processor fan are tilted about 30 degrees so there's plenty of ventilation. Thanks for checking it out!
