As a shamless Pismo lover (I use mine instead of my G4 1.2 GHZ iBook) I am very interested, what, exactly do you mean? Part by part, to build a stock/upgraded Pismo or using the Pismo case with more modern "guts"?
PB G4 15" 1.2ghz - Pismo G3 400 mhz - iBook G3 500 "Jukebox"
"SawSmurf" G4 500 - Quicksilver G4 Dual 1ghz modding...
