Looking for a cheap mb that supports PC2100 ECC - Any help?!

[Severe]

Title pretty much covers it all. I'm looking for an inexpensive, preferable micro-atx (but that's not a requirement) motherboard that supports DDR Pc2100 ECC ram. I've got a gig and a half of the stuff laying around and I would like to use it for a small server.

Thanks ahead of time for your recommendations!
