OK, I'm brainstorming...
-Has anyone seen a current ibook G4 logic board or compared it to a 12" powerbook board? I'm wondering if the ibook board is capable of running a 167MHz bus with a resistor swap (sort of like how the original dual-USB ibooks could be bumped from 66 MHz FSB to 100 MHz by changing one resistor). Something tells me the 12" PB logic board shouldn't be too different from the 12" g4 ibook, given that they're now using the exact same model G4 chip.
I'm dreaming of taking a 1 GHz ibook, upping the bus to 167 MHz, (overclocking it to 1.25 GHz in the process, which shouldn't be a problem on a recent G4), replacing the slot-loader drive with a tray-loader and the opaque slot-load g4 plastics with painted crystal tray-load plastics.

A: The boards are very different from each other
B: I dont personally think it will run at 167MHz, athough if you are proficient with solder 402 sized parts you could give it a try.
C: The fact that it has a 7547 doesnt mean it will for sure be overclockable by 25%. Thats a fairly big jump. (like going from 400 to 500 on an older G4). It may or may not run at this speed. It may also need a voltage boost to do it.
D: As far as I know, G3 plastics wont work on a G4, they mount differently.
Why do I keep reading people wanting to replace slot loaders with tray loaders? Kinda going backwards isn't it?
AFAIK its so they can use the clear G3 plastics on the G4 iBook ... keeping the slot loader would leave a fugly hole in the side of the case ...
