I bought a new-in-box Tiny PC. They were a British budget PC company that were doing the "Whole PC for £500" in the late 90s. We had one in the late 90s so I was pleased to find this PC / Case.




It came with an M-ATX Motherboard, 300MHz, 64MB 100MHz RAM, 8MB ATI Rage Pro Turbo, PCI modem and an ISA Slot.



Unfortunately I sold the motherboard because: It didn't want to work with Katmai CPUs and the PSU was really loud so it wasn't really usable as a system, and slower than my ATX Slot 1 PC.

Aaaaanyway I now have a new SFX PSU so I am hoping to put the case to good use. I want to make a Windows 98 PC with it but the case isn't very compatible as it only has 6 stand off holes for the "narrow" kind of MATX. I don't have a threaded drill bit thing to make more holes for the more common "wide" M-ATX and there is a hole where one of them would go anyway!

(ehhh I have no idea how the spoilers work for this...)

TL;DR
So I am after a Windows 98 compatible narrow M-ATX board which has AGP, PCI, ISA would be nice, and only uses 6 scews. Needs to be Socket 7 to Socket 478; Slot A to 939. The later boards need a proper southbridge for PCI Audio.

So far I've found an ASRock P4I65G which looks like it could fit the bill.

My other option is to put an AM4 board in there with a 1600AF or something!
