Err no - quite the reverse. It's the poor man who wants to squeeze out every last drop of performance from their computer
I'm surprised that so few 68KMLAers are adverse to Mac overclocking to be honest! Sure, some classic machines you wouldn't go near but when we're trying to attain the best performance we can from older components, it makes sense to me. Of course you need to have good soldering skills, and yes there are potential risks, but with practice it becomes quite straight forward.I also enjoy overclocking older Macs, I've never killed one, and if I ever did parts can be replaced cheaply. A lot of Macs I've come across lately have been slower machines (eg. PB 550 when PB 667s were around, PB867 with PB1000s, etc), and all have overclocked to the next iteration of Mac clock speed, or above.
This is the best guide on how to overclock Dual G4 processor cards for a 100Mhz bus speed. As Quadraman noted, if running on a 133Mhz FSB Mac, you'll need to adjust the multiplier according to this speed - easy to work out.

If you need any more tips on how to remove the resistors etc, let me know.
