The model of my PPC is a A1095 I see you guys using your PPCs as daily machines and they are all modded and decked out with icons and themes and such. . Mine has been decently upgraded with 1.5gb of memory and a 160gb drive. I have 10.5 on it. I use TFF have some programs on it like an old version of Spotify and Diablo 2. What else can be done to make one more usable in 2015 by way of optimizations or customizations. I may be asking much. I don't know. I'm a complete noob in the PPC community. Thanks!
