Oh by the way, you should also consider a UPS in cases of power outages.
APC is very recommended.
I run a SmartUPS 1400 for the Pro (should also be plenty for your machine) and a BackUPS 650 for my displays.
It's not cheap to get an APC in Australia... I would know since Ive looked a bit and haven't found any in the great price ranges you see in America, really annoying. Unless I've been looking in the wrong places or something. Perhaps some other Aussie here might shed light on it
