I am building also a 486 retro system. After checking many forums, also at this site, i found the best motherboard is the Biostar MB8433-UUD. They only have problems with the Dallas chip. However somewhere i have seen there is a hack for it and possible to solder a battery on it.
Further I will add an Intel 486dx4 100mhz CPU, 32MB SIMM memory, Matrox Millenium I 4MB VGA, Sound Blaster awe 32, combined with DOS and Windows 3.1. I also found a Creative Quad speed CD reeder and 5.25" floppy drive from Panasonic. These all will go into a modern house, like Fractal Design R6, but I did not yet decided at this point.

So something like this guy has made here:

Just my 486 will be even better :). I careful not to choose newer hardware than 1995. I think that was the last year when 486 was still considered as serius machine.

Hope it helps you!
My high end of '96 gaming machine;
Intel PR440FX - Pentium Pro 200MHz 512K, Matrox Millenium I 4MB, Creative 3D Blaster Voodoo II 12MB SLI, 128MB EDO RAM, Creative Sound Blaster AWE64 Gold, 4x Creative CD reader, Windows 95...

I have found out that it is really more trouble than it is worth trying to build a 486 computer with todays used parts.
It's hard to find good parts and it is a gamble to buy used parts.
It is much easier, reliable and less expensive to build a DOS computer with modern parts like many You-tubers have mentioned.
A Super Socket-7 Mother board or a Slot-1 BX-440 or BX-443 Motherboard with Pentium-3 500mhz will do just fine.
They have a NEWer bios that can support larger hard-drives and you can configure the bios to slow down the CPU performance for playing old DOS games.

486 parts are really beginning to get expensive these days. Yes that is true. If you are thinking of doing a "phils 4-in-1" SS7 multiplatform solution. Then I am afraid that you will use way more money, than a 486 these days.

Unless you get something donated, or you are extremely lucky at a local sale/flea market. A gigabyte GA-5AX are near impossible to find, and when they do pop up, they cost at least the same as a 486-board + VLB-Vga + CPU. And that is for the SS7 board alone.
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick I tell.... (never tried though)

A common socket 7 motherboard can be an acceptable substitute, especially with a PMMX CPU.

I’d argue even a better solution, Triton chipsets are very solid and you have great setmul support for spead flexibility. My main system is a Pentium MMX 233 and I wouldn’t swap it for anything else as a main dos system even though I own pretty much all the other setups including one of the best SS7 motherboards ever made.
