I'm using a PB G4 1.67 GHz running OS X 10.3.9 and Kubuntu Linux 8.04. Because I love water so much, I'm planning on making an aqua-themed PowerBook, making whatever I could blue/aqua. That goes to installing Kubuntu Linux, Unsanity's Shapeshifter, ClearDock, some icons, and my handmade wallpapers. All I need to do is paint the casing some shade of blue and decal it with a large K. My grandfather's house has some spray paint. But I'm not sure if I should use it on metal. Any of ya'll have any ideas?
