oh, I see. Its just that I see that acronym in a daily basis on my office lol.
quick question!
I have no problem for the storage (mini server with 4 tb caviar green)... Should I get something else instead of the Caviar Blue?

imho 320-500 GB are more then enough at the moment
Make sure it's 7200rpm HDD , any 80-250GB HDD will do
Stock Caviar greens cause stuttering due to intellipark
