i've got 1 piece 512MB PC2100 SO-Dimm new in package for sale.. $50 shipped from sunny southern california via USPS Priority Mail.. I paid 69 at Frys about 2 months ago, purchased a different motherboard and never even used this ram. I'd return it but they wont let me after 30 days.. so I offer it to you. I'm also looking to buy quite a few items and will accept them as trades please see the link in my sig.
