My VERY first computer was some Tandy-looking setup with an ungodly green display. I couldn't begin to tell you any system specs. It had some version of Ms-DOS. Very old and tired.
My REAL first system was a Fingerhut special...Cyrix 233Mhz chip on some mobo that was SUPERGLUED to the case...a 2gb hard drive....32mb RAM (i think), and a CD-ROM.
The first system that I built was basically a hand-me-down system of my older cousins (who originally got me into this comp-tech thing). P3 700Mhz, Asus mobo (can't remember exact model), 8gb HD, 32mb video card, generic sound card that came with system listed ^^above. Cousin originally put all the parts together, and basically sold me the main parts that he was replacing, and we put them together with some of my old Fingerhut leftovers.
