    I wasn't going to use it myself, but give it away to my nieces, girlfriend, family and such as presents. I thought about perhaps using them for light weight webbrowing or a Retro Machine.

    Don't forget the possibility of using it/them as an electronic picture frame as some have done. But that might be overkill for power consumption.


    However, my question was more in terms of what the chances were of it working if I changed the capacitors myself?

    I just did a ASD test on the machine and the one test that failed (from what I could see) was the PCI ATI VIDEO CONTROLLER test which said "Data Mismatch Error" error testing failed. I was able to see a little which said in the system info that the CPU was a W8 CPU ID. Does this help?

    It was moving as well the redesigned cursor However, there were no artifacts other than that.

    You were given some great advice over at MacRumors in the same thread you started there. Nick has more or less confirmed what was already said to you in that thread. Just saying.....

    One quick warning. A large percentage of those Caps are blown. If you keep using that machine with those Caps. you will do more damage to the machine. I owned the very last iMac G5 that had the same case and basic design as the Intel macs that followed and using it with those tented caps caused it one day to GO BANG. Literally sounded like a large fire cracker going off inside the iMac! When I took it apart the one cap blew it's insides out all over and did damage to the Power Supply and the other one took out the SATA controller. After that the machine was history.

    If you want to keep working with that iMac, please change the caps asap.

    Thank you for your advice! At this stage I was trying to gather as much information as possible. Do you think changing those caps would do the trick? Or do I have to fix the GPU as well?

    seriously the only to find out for sure is change all the tented/blown caps and then see what happens. It could fix the issue but at this point no one can say yes for sure.

    The later G5 iMac was such a pain to get apart and it seemed ok that I never checked. If I would have checked sooner that machine would probably still be working today.

    I bought a set of caps one time for an iMac. I think they were around $15-$20. Might have gone up in price...it was a while ago.

    As Dennis said...change the caps & see what happens.

    I was actually thinking about buy two more of these if these could be fixed. Some of the other models were beyond repair I guess. But, I will start with this one and see how it goes. Hope the work is not wasted.

    I have a small update:

    Now I have two iMac G5 20" machines! Second one seems in better form. I was thinking about reflowing the GPU with a gas burner lighter as suggested by someone. I've also seen it on YouTube. I guess using flux would be a good idea apart from changing the capacitors. What are your thoughts on this?

    I kinda already commented on this earlier in the thread (GPU reflowing & You Tube videos on it).

    All I can say is good luck (really...I hope you are successful). But don't be surprised if you end up with a permanent doorstop.
