I decided that I need to build a retro-gaming system. DOS gaming is easy enough to do on any sort of computer, but I had a real problem with early DirectX titles. A lot of them puke on screen resolutions above 1024x768 or on NT-based OSes.
My main requirement was that I had to have hardware supported by Windows 98, but still capable for gaming.
I wound up with a P4/3.2GHhz on an i865 motherboard, 1GB RAM (overkill for Win98), 160GB IDE drive, AWE64 and a Radeon 9700 driving a 15" 1024x768 flat panel.
The trick in all this is that all my components except the video card wound up being new in box parts. Some of it was just crap I had sitting around. I had to go hunting for a new motherboard, but it wasn't hard to find. It was a lot easier to find a new socket 478 motherboard than it was to find a new Socket A, though.
The whole setup is pretty sweet for stuff like the old Microprose Magic: the Gathering game, or Mechwarrior 2.
The only way I can think to make it better would be to add in an SSD.
