The AT case with mystery insides arrived the other day. I'll post pics of the insides this evening.
I was originally planning on using the case for an build using an ASUS P5A-B and K6-III+ 450 but....
The motherboard is a SIS based PCI/ISA Socket 3 board and the CPU is an AMD 5x86-133. 😀 Both of these I was wanting but not wanting to spend what people were asking.. especially for a PCI/ISA 486 board.
So now I will probably just leave the motherboard and CPU in there.
Finding AT cases for a decent price is such a hassle. 😒
Edit: pics of the motherboard below.
It is a Jetway J-446a V2.0

Manual shows it supports up to 50Mhz FSB.. but there are a bunch of jumper combination settings for the FSB jumpers that are not used... hmmmm. I think I may have to do some experimenting. I'll probably look up thew datasheet for the clock generator and see what it actually supports.
The Turbo function can either be controlled by a turbo switch/jumper or with a key combination.
Looks to be a really interesting board.
When it arrived, the CPU was all the way out of the socket and some of the pins were bent. The RAM was also dislodged and I had to reseat all the cards. Also had to reattach the one com port to the back of the case because it was missing both lugs.
The CD-ROM drive will not eject, even after opening it with a paper-clip and then having it close with the button. Not sure if it is worth taking the cover off to try to fix it.
The stick of RAM that came with it seems to be bad as it would just give me a constant beeping like there was no RAM installed.
The video card and sound card are both ExpertColor branded.
The video card is an S3 Trio/Virge and the sound card is Opti 931 based. The other card is a modem.
HDD is 2.1GB which will be replaced with a CF card.
It boots to Windows 98 with nothing at all interesting on it. Just a plain install and a couple games.. Some Barbie Game and a Thomas the Train game. I'll probably poke around a bit more before taking the drive out.
