Thats the dumbest thing I heard all day. I built my first computer at 11 (one for my grandmother) and built my own when I was 13 (I recently turned 14). As you can see, my build is completely reasonable, coming from hours of research into the topic. I'll also mentioned Im pursuing a career in Electrical Engineering, studying Pre-calc, Trig, and Differential calc, and have built many electronics projects with my own knowledge. As Tallon said, Intelligence =/= age
