If you're just getting into retro computing, this isn't going to be an easy rig to acquire and setup. How serious are you about doing this?

Correct.
To stay in 1999, make sure you get the original Athlon 750 with the Pluto core (AMD-K7750MTR52B A), not the year-2000, integrated-cache Athlon 750 with the Thunderbird core (AMD-A0750MPR24B A).
For 1999 motherboards, the choices are: AMD Fester, MSI MS-6167, Gigabyte GA-7IX, FIC SD11, and possibly the Asus K7M. I can run down the strengths and weaknesses of these boards, if you'd like. Just make sure to avoid early revisions of the MSI and FIC boards. Other AMD 750 boards that may be 2000 releases are the MSI MS-6195 K7Pro and Soyo SY-K7AIA. Tracking releases of first-gen Athlon mobos is difficult, because in order to appease Intel, vendors did little to promote their AMD 750 boards in 1999.
You will need the right PSU with sufficient amperage on the 5V rail to power this. AMD had a list. The FIC SD11 apparently had a list that was narrowed down still further. You will likely need to decide between risking an old, period-correct PSU (possibly damaged), or purchasing a modern, high-wattage PSU (overpriced, horribly inefficient at the load you will be pulling).
For the graphics card, I was going to suggest ATi Rage Fury MAXX, but I'm not sure they actually got these into the hands of consumers before January 2000.
