Well, apparently I never updated THIS thread with the changes - instead I ignorantly necro-posted without actually reading back to find out how updated the thread is.
Current status of build:
Sitting on my shelf, but mostly together.
I got an ATX case from someone, but it was an entire computer: an IBM Aptiva E85. This system is an AMD K6-2 300MHz processor, 64MB of SDRAM (32MB x 2 @ 66MHz), a 6GB Quantum Bigfoot XT hard drive, and a CD-ROM drive. It originally had Windows 98 Second Edition, but I had to use the Quantum Bigfoot to test out the Windows 95 install, so now it has a copy of Windows 98 FIRST Edition on it again (all I have at the moment). All drivers are installed properly and functions well, though I did swipe the CD-ROM Audio cable, so now I have to find another one to restore that system.
I used that case for a short while to hook up my Pentium build and it actually worked. I got a 20.4 GB Maxtor hard drive that I was able to find Overlay software for. The Motherboard doesn't support hard drives bigger than 8GB, so that made the overlay software necessary to access the full 20 GB of space. Once installed, it works like a charm. Windows 95 OSR2 is installed, I have the motherboard's built-in sound chip (a Creative Labs Sound Blaster Vanta chip, it's a 16-bit SB compatible) installed and working, used a fully-working ATI Rage IIc 4MB PCI graphics card (more period correct) and also have my extra Voodoo2 8MB card (a Diamond Monster 3D II) installed and working. I have no pass-through cable, though. And yes, I know the 200MHz Pentium is holding the Voodoo2 back...but a Voodoo1 is still over $50 on Ebay. I'm not willing to pay that and I already have the Voodoo2 card - might as well use it for something. Hell, it'll probably work better in the K6-2 system, but I haven't fully decided anything here yet.
While I had the Pentium system hooked up, I installed a number of older programs like Star Trek Encyclopedia, SimTower, SimCity 2000, Carmen Sandiego games, Duke Nukem 2 (the old DOS side-scroller), Duke Nukem 3D Atomic, Quake 1 & 2, Doom, Wolfenstein 3D, Microsoft Office 1997, and even ran 3D Mark 99 Max, even with only 40 MB of RAM. Now I can run with 64MB and 3DMark won't whine at every start.
I'd still need a generic ATX case for this built - and a CD-ROM drive, but other than that, this build is complete.

I actually spent a bunch of time on this system while it was together teaching myself about DOS and memory management. I ended up getting DOS mode down to only 19KB of conventional memory used WITH CD-ROM support and mouse drivers running. It involved learning how to configure CONFIG.SYS and DOSSTART.BAT to enable HIMEM.SYS and EMM386.EXE to access high-memory areas outside of the 640KB Conventional Memory space. I mean, I have 64MB now....should have a lot more than that tiny amount. I don't even remember memory space being an issue back in the early 90s when using DOS. I guess my father already had his systems configured for it.
