Similar background re: PC building here, working at a shop that built PCs in the late 90s. I remember seeing boards with these new-fangled USB ports, DIMM memory, Pentium II, the first 3D accelerators, etc. It was a fun time. I got in to the industry right at the end of AT-style boards and power supplies and mostly missed having to deal with that stuff (other than in my personal life, where I still had old stuff).
