several months ago i purchased a completely disassembled powerbook g4 12" 867mhz at a yard sale for $25 with the intention of rebuilding it. it needed more work than i thought, so i built it into a backgammon case so it would have hinges. the bottom 1/2 is almost complete, only the cable to the dvd drive broke, so i took that out. i recently purchased the main thing that i needed, a cable for the hard drive. does anyone have any ideas for a cool mod? i would love to have a touch screen, but then i don't think it could be run off of a battery, and also i have a very limited budget.
