i've got some server grade, Kingston 533mhz PC2 4200 Registered ECC 240pin RAM here. its two 512mb dimm's, giving you a whooping 1GB of RAM. I got it off newegg brand new for over $100 last week...only to find out it doesn't work with the server we're building. I'd rather not deal with newegg's RMA, so its your's for $75 shipped, obo.
