Hi Tom,

Regarding G5's and G7's....
We have them both (all though not for asterisk) at work. and found a
little snag.
The purchase department interferred with our initial ordering of the
hardware. As a concequence, they did not order the battery for the raid
controller. (seems you have to order that explicitly)
After it arrived, we were able to install linux on it and use it, but
disk-io was way slower that the original G5.

You might want to check/compare disk-io & throughput on your G5 vs G7.
Just a thought....
