My first computer, (after the apple IIe clone I used in college)was one I hacked together from old parts. Most of the parts were from my parents' first computer after they fried the mother board. I found a mother board and for about 3 years, just kept adding and upgrading components. Probably doesn't make sense now but at the time, a new basic computer was probably over $2,000. We called it the frankenputer.
