I think most ppl who build pc's or build anything for that matter, started with Lego.
I had boxes of it as a kid, all the spaceship stuff, like this


then it all went as a teen, then in my 30s when i can actually afford the good stuff i got hooked again! technic is great, but id love to try out the mindstorms stuff

could make an interesting project
