So I have a question, would I be able to swap boards between Macs? I have my new 2.0Ghz dual board that has 8 memory slots instead of four like my 1.8 dual. Both of them are from the same time period. I would switch the board and processor. I would just put the HDD and ram in the 2.0, but the case is scratched up and it has writing on the door. They were both made at around the same time (mid/late 2003). Also just got my airport card in!
 
As long as you keep the 2.0Ghz processors with the 2.0Ghz board you'll be fine. You will have to run the ASD thermal recalibration to get the fans to be able to idle.

Great! Now I have something to do after work! Also, what is the ASD thermal recalibration?
 
ASD stands for Apple Service Diagnostic/Disc. They were/are discs that are not released to the public. You need a certain version, 2.5.8, to recalibrate the temperature sensors on the CPU boards. Once a processor has been removed from a G5's logicboard, it must be recalibrated. Without recalibrating, the fans will be in a failsafe mode were they will run at a high speed non-stop.

Do you know where I can get a copy?
 
Can't go into detail on that as it constitutes as piracy, which is not allowed on MacRumors.

Man, you learn something everyday here at MacRumors!
Being a laptop and not desktop guy, I would never had known this.
 
I am proud to say, I am successfully typing this on my wireless G5! I made a genuine apple antenna! I used a spring from a PowerBook G4 lid latch. Added some aluminum foil, and BAM! I get full bars. I plan on using this thing alot more now that I have internet access. Very happy with this!!! :D
 
No as well. The fastest external bus for a G5 is Fibre Channel, 10GB Ethernet, or FireWire 800.
...and eSATA, either with a card that has this or with routing an internal SATA-port to the outside, with a pci-slot-bezel.

Would he still have to recalibrate the fans, if he swapped everything to the good case? Does one have to unmount the CPUs to get the logicboard out?

It depends on the G5 model. I've always recalibrated the fans when removing any CPU.
 
I don't think I will be swapping boards. I don't know if the board I am going to use is going to work. I get the common "two click" problem when I plug the system in. I swapped batteries and still nothing. And the other system I have works, but it is a very dirty system and it looks like it sat in a moist place for a while. It has some rust on the front power button panel... I think I will just stick with my Dual 1.8. It is a clean system, and it performs and looks great! I will try to get the other two systems running, then hopefully sell them for $30 to $40 a piece with no HDD. I did manage to get a ASD disk but it is 2.5.7. Oh well. I am happy with my system. Plus, I never would think about putting 8GB of ram in one of these. I'll stick with 4 because I don't think I would use any more than that.
 
I think ASD 2.5.7 will work in your machine. The clicking it caused by the relays in the power supply. Most of the time it is completely normal when plugging and unplugged the machine.

Yeah but it clicks when I try to power on as well. So is there any way to fix this problem?
