I used to dig through old computers to see the snazzy insides, and them put them back together differently. I was in sixth grade, if I remember correctly. Who cares about the story, here are a few nifty pictures:
This PC was actually known as "Skippy" for about five years. It has served admirably, holding eight gigs of music, and made enormous Worms World Party LAN matches possible.
I tought myself how to disassemble, reassemble, and install Linux (Slax was the first distro I tried, then Ubuntu. Later I started using Knoppix).
The motherboard was just left on the floor, for about two months. Worked just fine.
