I still need to decide on the RAM memory.

Western Digital 320 AAKS, Hd4850/70 are almost here.X360PS3AMD05

What about WD? Is it a new HDD or something?

Yes, some people are getting them, single platter, quiet, almost as fast as a Raptor IIRC. http://www.newegg.com/Product/Product.aspx?Item=N82E16822136074 I'm waiting for the Samsung F1 320GB to be in stock they only have the 500GB i think that one is as fast or faster than a Raptor with its single platter. http://www.newegg.com/Product/Product.aspx?Item=N82E16822152098X360PS3AMD05

How do you know its new technology though? Where does it say?
