Fixed the title for you.
By the way, the only reports I've heard of RAM from NewEgg not working in Macs is with a certain 1 GB SO-DIMM (laptop memory) made by a company called "Kingmax." I've seen one or two people say that they got this for their PowerBooks and it didn't work. So you can probably still go to NewEgg, but maybe just avoid the Kingmax RAM. I think desktop RAM is generally less fussy anyway.
