I plan on buying a G5 1.6 this week (assuming no big announcements) and wonder: 1. What manufacturer of SATA HD is recomomeded - I ant to add a second 80 G SATA drive for backup? 2. What speed RAM PC2700 or PC3200 - and will it make a diff in this machine? I was planning to add another 256 to a total of 512. But would taking it to 768 make a noticable diff for "normal" office- like tasks (no PS or Final Cut, etc) Also, where is the mac shipped from/assembled?
