Cooling Mods for iMac G5?

Question

I have an 17" iMac G5 (original) and use it all day. I suffer from the constant fan noise as many users here do.
I've noticeed that later revs of the iMac have additional vent holes on the back casing to allow for additional airflow to cool the system better than my original model iMac G5 which only has inlet vents along the bottom of the case.
I'm wondering if anyone has modified their iMacs to allow for additional cooling and if it made the unit quieter. Hopefully, the mod doesn't involve physical modifications like cutting as my iMac falls into the range of serial numbers that are covered by the extended recall warranty for the bad capacitors.
Thanks!

I totally agree with the "getting on the phone and complaining until the issue is fixed!" I did what alot of Mac-friends said couldnt be done. I had my iMac G5 replaced 2 months after the expiration of the waranty.
I had a rev A iMac G5 20 incher. Over the course of its first 11 months it had to be fixed 5 times. The issues, in order were-->failed inverter, failing optical drive, failing motherboard, failing power supply and finally the last issue i was having was a bad inverter AGAIN!
Now I know that they ( Apple) has issued an extension of the waranties on many of the first generation iMac G5s' but this one wasnt on that list. ( Supposedly!) But I was dilegent and wouldnt take "NO!" for an answer. They kept telling me that they would send me one more inverter and if that didnt fix it once and for all, they would then replace it the next time it broke down. I just couldnt or wouldnt do it that way. I mean, like I told the Apple Rep. I had had so many issues with this computer that I had begun to think that the machine had been abused before I got it somehow.
The Rep, had to call me back 3 times and kept trying to just send me one more part to fix it. But I just wanted out from under the darn thing after having had so many problems, and MAJOR ones at that! I remained calm the entire time, was respectful of what the rep. was trying to do but politely declined his offer saying that " I really just want my machine replaced, or maybe just give me my money back and I'll go elsewhere. " I explained " I am becoming concerned about the longevity of Apple products at this point! Maybe I'd be better off with a different manufacturer." It was at this point the rep. once more asked if he could call me back in 30 minutes. When he did, he said the new machine would be on the way. And not only did they replace the machine but they also replaced the 2gb of memory since my first gen and the newly availble rev c or iSIght iMac G5 used different memory. ( My 2gb of ram from the rev a. would be useless with the rev c. iMac G5.)
A long story i know. But its proof that sometimes you just have to stand up for yourself and let the evidence speak for itself. Sometimes you have to be patient and I really think that if you start cursing or insulting reps you wont get far at all. Just be calm, treat people as youd like to be treated and dont take no for an answer.
Anyway, this is a bit off topic but I wanted to relate it to anyone interested.
