First post on the forums.
Presenting you 3 retro "battle stations", resembling PCs from 1990, 1993 and 1996.
Getting them up and running was quite a journey - going back through my memories, identifying and finding components, restoring them, putting everything together, breaking and fixing stuff (nested loops).
During my research phase i realized that many of us often mix and match components from different generations to achieve best/worst performance, better stability, other more obscure goals, or because that's what we had on the shelf at the time.
Instead, i wanted to stay true to the given platform and its time period. So, i avoided any DLC/POD upgrades and made sure that no piece of hardware/software is from later year than the one marked on the calendar.
Well, with one exception - after couple of setbacks with failing old HDDs, i ended up substituting them with CF cards. For now ...
What else ?
Any overclocking and other tweaks had to be long-term stable. End goal was to build computers that work for real.
No ATI video cards.
Looking back, i realized that somehow i never owned ATI hardware.
Well, except for a FirePro v7900 couple of years ago, but it was donated by ATI, so it kind of does not count. Wonderful card btw !
To keep the tradition alive, i passed on Wonder/Edge-16, Mach32 and 3D Rage II for the 3 rigs, respectively.
No Pro 3D accelerators.
I guess my choice of timings was less than ideal considering the situation with Pro GPUs back then.
In 1996 - Intergraph, 3DLabs, Dynamic Pictures, etc., were targeting Pentium/WinNT systems with their second generation 3D accelerators, but not a 486/Win95 one. They didn't even have proper (or any) drivers for Win95. At some point i considered strapping GLINT 500TX/DELTA, or Oxygen, but then common sense prevailed and i went with cards that are more natural fit for the system.
In 1993 - Everything interesting related to 3D accelerators for the PC was happening on the 486/VLB and first Pentium/PCI systems, but not a 386/ISA one.
In 1990 - What professional PC 3D cards ? The low/mid-end pro graphics was Amiga territory. There were handful of CADs and pretty much no graphics software for the 286.
SoundBlaster fanboy ?
Not really, just being practical with the sound setup, with focus on compatibility.
Never owned a GUS for example. The curiosity is significant, but the prices are chilling. 😀
Computer cases:
I didn't want to hide the carefully selected and assembled hardware inside standard PC cases.
Instead, i modified 3 ATX acrylic ones to fit the AT components. This took a lot more work than expected, but the result was worth it, i think.
286 from 1990
Some of the best 286 designs emerged around that time. The platform was in its prime, but with 386 rapidly growing in popularity and the first 486 systems introduced to market the year before - writing was on the wall already.
Still, highly integrated 286 chipsets kept showing in the following 2-3 years, but they didn't introduce anything more interesting than compact form factors.
Piece of sweet memory:
I clearly remember the moment when i saw for the first time VGA graphics on my 16MHz 286.
Shaky fingers swap old CGA card and monitor with fresh VGA ones (Trident + 14" 0.36 dpi CRT). PC is on, first game shows-up on screen and ... where is my jaw.
Today people think that Apple keynotes are magical.
Sure. 😜

NOTES
The system works really well at 25MHz with 0 wait states and 30MHz with increased wait states, but it took quite an effort to "climb that mountain". For example, finding the right memory modules was a memorable experience by itself.
No SCSI ?
The top SCSI controller at the time AHA-1542B is actually slower than what this motherboard does with IDE.
SCSI's max data transfer rate is below 2.8Mb/s (all settings on max), while the IDE goes way over 3Mb/s.
[EDIT] The story evolved with:
Improved ventilation, complete long-term stability: Re: 3 (+3 more) retro battle stations
and 27.5MHz + Cyrix FPU FTW: Re: 3 (+3 more) retro battle stations, probably the fastest 286 class PC around here.
Upgrade with TI 486SXL2-50 @66MHz CPU for extra cool (or weird).
And the latest development - evolution to 30MHz and 0 wait states.

386 from 1993
Until then a good 386 system was able to hold its ground (well, more or less) against an average 486SX/DX one, especially if one considers the price-performance ratio, but the newer 486DX2 designs from 1992 changed that for good. Around that time 486 became the mainstream and the first Pentium CPUs were introduced to market. This indicated the end of the platform.
Another melodramatic insert:
Summer job paid for a shiny Sound Blaster 2.
Bought it. Back to the bus stop. Every minute is eternity. Bus finally coming.
Back home. Installing. Connecting the sound system with beefy speakers. Starting Dune 2. Watching the intro.
Transformative experience.

NOTES
Speedsys gives lower score for 386 CPUs if FPU is present. All other tests indicate consistent CPU performance.
Increasing the L2 cache to 256Kb and adding WB chip improves performance by couple of %.
The system works really well at both 40Mhz and 45MHz with 0 wait states.
When at 45MHz it requires "cool-down" time between cold restarts. Significant effort went into identifying the source of the problem. At the end, it turned out to be the cache chips being very sensitive to heat. Will slap active cooling on them at some point soon.
Cyrix's FasMath CX-83D87-40-GP (black top) is actually slower than CX-83D87-33-GP (gray top) by 2-3%. This is confirmed by the rendering tests.
A hint in this thread A brief comparison of 386 FPUs sparked my interest to compare the two more carefully.
S3 928 does not cooperate when the CPU is running at 45MHz.
Also, despite the 2Mb of installed memory, the driver maxes out at 800x600x8bit in Windows 3.1x, which is disappointing, because the Vibrant driver tells different story.
A lot more disappointing was the fact that WinSprint's Windows 3.1 driver does not support High and True colors either. Real shame for such an amazing GUI accelerator.
*UPDATE 2020-01-26:
The PC-Chips M321 motherboard has been replaced first with Forex FX-3000 and then with DTK-PEM-4036Y - probably the fastest clean 386 class PC around here.
*UPDATE 2020-05-03:
While the initially used Sound Blaster 16 CT1750 v4.05 is period correct for year 1993, it just didn't feel right for 386 class computer, so Sound Blaster Pro 2 CT1600 took its place. It is a more natural fit for this PC.

486DX5 from 1996
486DX5 was introduced at the end of 1995.
Pentium took-off for real in the mid 90-ies.
Some of the best 486 designs emerged around that time, but also, these were the last golden days of the platform.
Last one:
From early age i was feeling artsy ... or something, so i had this urge to visualize my ideas. This was bad for the trees.
Once i got into computers, the understanding of what they can do in regards to art quickly trickled-down my head and in the mid '90-ies i found myself with a massive interest in computer graphics and software development.
Of course, the results i produced at the time were not exactly impressive, so the only real measurable effect was my desire for powerful hardware.
That second part was unpopular at home and the 486DX5 had to be the popular hardware of choice in my room.

NOTES
My favorite motherboard.
It smells and feels 486 (socket 3, VESA, FPM, PIO 4), mixed with the right set of "next-gen" tech (PCI, PnP, on-board IDE), all wrapped in a fast and reliable package that just works.
This was the product that made me notice the ASUS brand back then - a gift for them that keeps giving.
Increasing the Level 2 cache size to 512Kb (from the default 256Kb) improves performance by 1-3%.
For example, Quake 1 went from 16.9 to 17.3 FPS.
The system works so reliably at 160MHz with the AMD CPU, that i don't even consider it being overclocked.
It looks like the 1996 ADZ version of the AMD chip is a tiny bit slower than the BGC one from 1999.
For example, Speedsys shows score difference of 0.04 (59.94 vs 59.98). This is confirmed by the rendering tests as well.
The Intel CPU running at 120MHz completes all DOS games and other benchmarks, but is unable to finish, or sometimes even start, any 3D rendering tests.
Why no SCSI ?
Not convinced that the SCSI will outdo the current IDE performance of about 10 Mb/s. Will verify at some point later, but for now is low priority.
