Late 90's vintage gaming PC + Sony monitor (no GPU) - $50 (buffalo grove)

Some years ago I built a vintage gaming PC with brand new parts all around.
All all high-end components for the late 90s period of time.
It is in the basement but worked last time I used it, but doesn't have a graphics card anymore so you'd need to obtain one to use it.
Tualatin based Pentium 3 CPU 1.
3GHz speed, 512MB RAM, Intel brand motherboard, a SoundBlaster Live! sound card, Windows 98SE, CD ROM drive, hard drive, and a number of high quality games from the time period pre-loaded (lots and lots of high quality games on it).
There is also a Sony 15" LCD monitor that comes with it.
It is 1024x768 and actually amazing picture quality, especially considering it is from that era.
It ran everything perfect.
Case - it is a more modern all black case from 2008.
It is either Antec or Cooler Master brand (sorry but I forgot the exact brand and model) and is a great case.
