Help me build a real retro-rig.

Yeah....I'm bored. And fiddling with old and cheap stuff beats wasting more money on modern and expensive toys.

Anyways, for some reason, I've always wanted to put together and overclocking a dual PIII-S Tualatin system. Getting the CPUs is easy, a pair of PIII-S 1.4Ghz chips goes for around 20$ on ebay, including shipping. I have plenty of SDRAM or DDR (Since there are boards for both types of RAM for S370) and I have everything else required for the build, except for one thing:
An overclock-capable dual Tualatin motherboard with an AGP slot that can run at least 1GB or RAM (2GB and up preferred).

Finding information about boards this old, especially when the boards weren't very common to start with, is very hard. Since there are people here who most likely were enthusiasts even 9-10 years ago, or simply people with a lot of knowledge in older setups, I hope you can put me in the right direction towards a few models of motherboard, for which I'll then hunt on e-bay.

If someone happens to have a dual Tualatin motherboard lying around gathering dust but in working order, I'd gladly buy it off you, as well !
