My 2x2 G5 has 2 - 250GB internals and a couple of 120GB externals, 23" cinema, and runs on OSX 10.2.8 (I have Panther 10.3.1 on my 17" PowerBook but waiting a while to install on the beast), and has been a dream. The only thing I have noticed is that when first booted, my video is kind of spurious, with artifacts distributed throughout the display. After restarting, this goes away. I have updated the firmware for the 9800, but to no avail. It is more of a nuisance than a problem since it only happens on initial startups and is easily corrected. Has anyone noticed this problem?
