To me the pentium 2-3 would be the most unexpected thing to see ^^

If there ever was an AT pentium 4 motherboard, it would be even more surprising

A few people have told me these boards exist, for industrial purposes. They're very obscure, but I have heard they go for hundreds if not thousands of dollars each (putting a lot of new technology in a board using a 30 years old form factor)

The fastest I've seen is an industrial board that takes supposedly all socket 370 Coppermine Celeron chips, but it was something like 800 dollars.

In my collection, I have a PC chips board with a slot 1 p2 400 mhz running in it, it's a board with socket 370 or slot 1 capability and is in a small enlight case, it's almost a retro sleeper rig 😀

I have 3 slot 1 AT boards. One is by PCChips and two are made by ATC I've not really used the PCChips one but the two ATC are fsb66 only unfortunately (LX or EX chipset). However using a slotcket, I could probably use a very quick celeron

A modern computer in an early 80s XT case would be hilarious. The monitor and keyboard would give it away though.

I think you could conceal the keyboard with either an AT model F, or a model M. I think it might even be possible to use the original XT keyboard with an adapter.
The monitor would be lot trickier, obviously.

There's actually a Socket 478 Baby-AT board made by Commell/Commate; the P4XB. Probably rare as hen's teeth, but hey... P4 in XT case! 🤣

Other alternative might be the SuperMicro P6DGH. It's a full size AT board with support for dual Slot 1 processors up to 600MHz and up to 2GB of RAM. Has onboard Ultra2 SCSI, nine PCI slots, an AGP slot, two ISA slots, and an onboard Intel i960 I2O buffering system with up to 64MB of dedicated RAM. Some people have had success running it with 800+MHz Coppermines.

Turns out there's also the Corvalent Gator AT; Pentium M / Celeron M Baby-AT motherboard.

Even though the top one seems to be excellent, the bottom one seems to be something like the "ultimate AT mobo" ^^ : because at least it would fit in about every AT case 🤣. And it's allowing you to make the most powerful PC with ISA slots while being able to use a very outdated case. That's probably the board that phil would need to make a "6 in 1 PC" 🤣

Wow both those boards look AWESOME. New ebay searches setup. Check. Probably won't get either one cheap.
