Is there a motherboard form factor that is older than AT motherboards and uses different screw hole placement than AT/Baby-AT motherboards?
I have a big case where I would like to put an baby-AT 386 motherboard, but I am having some trouble.
may be something proprietary?
Is this too much voodoo?
There is the "XT" form factor, but now that I own one XT system, I wonder if it wouldn't fit in an AT case

I think there might be something wrong with the motherboard itself that I think should have been baby-at size. It has alot of those small holes meant for plastic clips instead of screws and they are positioned differently than standard AT screw hole locations. I thing I would only be able to use 2 screws to attach it to the case itself.
It happens more often than you think. My 486DX4 is only having one screw, and my other 486 used to have only one too, until I changed it's case. Cases doesn't always have every screw holes that they should have

I have only one screw holding my VLB 486 board to the underlying plate, my 386 is the same way, and as is my Pentium. The only one that's a little different is my 386 in an XT case (top pops open type) which has two brass screws.

Two screws and two sliding plastic standoffs on all my Baby-AT boards.
If I put a plastic standoff to the left one at back of the case and a screw to the other one in the middle of back of the case, they match with the holes in the motherboard, but if I put plastic standoffs to the other 2 that are further away from back of the case, those plastic standoffs would be about 1cm too far away from back of the case to match the holes on the motherboard. How would you put motherboard in the case?
The motherboard that I am trying to put in the case is the one I am talking about in this thread: 386 KMC-A419-8 motherboard and ram

That's an XT case? Can you put AT boards in XT cases?

2 holes in the 2nd row (G and H) are incorrect. They are similar for AT, Baby-AT and ATX boards and must be 6.5" from the front edge of a MB (6.1" from the 1st row of holes). In other words - they must be below ISA slots, not between.
This MB not meets the Baby-AT standard.

It had a huge 286 motherboard 31x35cm when I got the computer and I would have wanted to upgrade it to 386
This is what originally came with the case. As you can see there is alot of corrosion.
