Hello, i am looking to buy a powermac g5 just for photo edition and other things like music conversion. i have a few powermacs g4 but i would like to have more power to make the things done before. nowadays is quite expensive to buy G5, but sometimes i see on ebay some xserve with dual processor in a pretty good price. and i would like to know the differences between the normal tower and the xserve. i expect the xserve to be nosier but with the same efficiency. thanks for the advices!
