lol I'm gonna ask my dad to teach me how to solder. I don't fancy teaching myself by practicing on a G4 board!
"Whoopsie, I dribbled solder across some chips... Oh well, can't be that important! *puts the G4 back together, plugs it in, and presses the power button* Oh noes! The Magic Smoke is escaping!"
You've certainly got a lot more courage than me when it comes to fiddling with prized Macs - I got really scared about pressing the cuda button on my G3, let alone soldering on its board! (if I knew how to solder
)
