d\I received an old Power Mac G4 400 as a gift, and would like to strip it down and customize it with new parts. Currently, the power mac only supports a maximum of 1 GB RAM. I would like to increase the RAM up to anywhere from 6-10 GB. Also, is there any way to install a new motherboard? I want this old computer to be a piece of High-Octane, Music Recording Glory machine. How can I go about doing this?
