I've been building G4 systems for some time now and what started as a hobby is exploding. What I have found out is absolutely no one makes replacement G4 power supplies! So your forced to pay $$$ for a stock supply. After I built my Gigabit system I kept getting kernel panics left and right on my G4 system. I found my stock supply couldn't handle the load and was becoming unstable causing the system to crash. So finally after lots of work I figured out how to build my own power supply that works flawlessly. It doesn't support the ADC connector but I found most hardware tweakers don't use ADC graphics cards in their systems anyhow. So now I'm offering these to any of you Apple freaks that are as Mac crazed as I am and like to build systems. I'm also working on a drop in replacement that would cover G4 systems such as AGP, Gigabit, Digital Audio, and Quicksilver. I'm also looking into an adaptor that you could plug into the motherboard and simply hook up your power, reset, programmers buttons to. This would also give your ATX case's power LED the glow when your system is sleeping. Just like Apple's case. So any tech heads out there interested in this stuff? Here's a pic of one of my babies. Later, A.J.
