Hmmm.
My first introduction to a PC was around 5-6 years old with Windows 3.1 on a Packard Bell. As well as the Pre-School I went to had a basic computer class. It was more or less on how to turn them on and off, and small games with basic math problems, etc. in them. Later in Elementary they had computers we would do basic math games and such on for a hour or so. Half the time I would get bored quickly with the ease of the games, and start trying to do other things on the computer (would get in so much trouble for that). Rarely did much gaming on PC even back then. Most of if any gaming was on my cousin's Game Boy or NES, or my Uncle's SNES. My parents where the type that consider video games as time waster like movies and TV. Most if anything I did gaming wise, or I consider interesting that was game related was board games (checkers, chess, Chinese checkers, etc.) and 1,000 piece puzzles (I was doing 100 piece puzzles in Pre-School).
After that did not really have much dealings with PCs until around 18-19 years old when I made friends with a guy in Comm squadron on base. Saw his computer and asked where he got it. He told me that he built it. Once I get interested into something especially if it entails building. I tend to go learn about as much as I can, and there is so much learn about computers indeed. Though, my first computer build was nothing fancy. More of learning the basics and seeing if I could at least get a basic computer built and running.
Now, it more or less a hobby that I highly enjoy doing when I can get parts to mess with. Plus, I'm almost done with my Associate CS degree which I should be completely done with mid next year. Of course I'm not stopping there as I'm very curious how electronics work at the hardware level and lower program levels hence I plan to go to a higher Uni for Electrical Engineering degree.
I tend to build mostly for tinkering and seeing what I can do with the hardware. Reason I tend to see gaming on PC as something extra a PC can do, and not a major reason to build them in the first place.
