Hi Its about a year or so old now but i recently found this when trying to find out about speeding up my old mac mini G4 1.25GHz computer. http://www.lbodnar.dsl.pipex.com/macmini/ If I was to open up my Mac Mini, I have 3 questions: 1. Can I just break these transistors off? (With some kind of pick or tweezer, small thing) 2. From the chart below, does 'yes' mean remove this transistor? Speed R362 R358 R355 R351 1.25GHz yes yes yes - 1.42GHz - yes - yes 1.50GHz - - - - 1.58GHz - yes - - 3. Using the picture in the link, also below, which numbers refer to which resistor/jumper thingy? E.g R362 = one on far right. http://www.lbodnar.dsl.pipex.com/macmini/macmini_jumpers.jpg They are the main things I'm interested about. One last thing, if I was to tackle this, what should I watch out for? Be careful about? I don't want to mess my poor old mac up. Any help much appreciated, thanks.
