Cool stuff ib_prime! And thanks for the info about the power switch ground. I'm going to connect the FW and USB shield grounds to a FW and USB ground, respectively. I know Cuzza said to run a ground straight from the PSU, but all the cables going to the front panel have already been sleeved and removing that to add one cable would be a major PITA. And running a single bare cable to the front panel would look... well.. you know. I don't have time right now to do this, but I'm gonna try really hard to get it done tonight. I also wanna get Win7 installed also. Oh, I don't know if I ever talked about the software for this thing. Originally, I wanted to dual boot OSX and some kind of Windows. I picked OSX mostly because I wanted to use Final Cut Pro for my video class. That's not gonna happen. Mostly because the teacher doesn't have one of those volume academic licenses where you can install it on any academic related computer. There's only one copy of FCP and it's in use. Second, the other Macs run some version of OSX that is not compatible with Intel Macs (so pre 10.4). So I would have to get my own copy of OSX. So no OSX here. So which version of Windows? I have a spare copy of XP, XP x64 and Win7. I chose Win7 only because it's newer and cooler. Edit: I've have just recieved word from the 'HelpDesk' people at my school that they've recieved their copies of Win7!! The head guy said that they'll be giving them out to a few select technically-savy students and I'm one of them! Sweet! So I'm definately gonna get the real Win7 on this Mac at some point in the near future (2 weeks). For now, I'll just stick with XP just to get it working. I've linked the other wire diagrams that I've collected. Unfortunately, I don't have their original sources, but I bet they're from Insanely Mac's forums. http://img.techpowerup.org/091018/G5 Front Panel Wiring Diagram 1.jpg http://img.techpowerup.org/091018/G5 Front Panel Wiring Diagram 2.png Eventually, I'll make a post with all the links and images/diagrams and such that I've used for this project.
