so i'm looking to upgrade. i have a dual 2.0 g5 with 8gb ram. if i get one or both of the following. a mbp 2.93 and a mp 8core 2.8. how can i use my g5 as a render machine and how can i use it as a raid box? how would it stack up as a direct storage device against let's say a caldigit hd pro. what would be the fastest possible interface to connect the machines? i would be buying a bunch of 3rd party pieces so i can fill the g5 with hd's. i already have 5 hd's inside it. i plan to put 10 hd's inside it if it can be useful for this purpose.
