The one we have at my office was purchsed immediately after they came out. At the time of purchase I upgraded to 1gb of ram. It's been running quite nicely all this time. I work for a newspaper and some of our machinery runs solely on classic applications, and occassionally things will malfunction and I have to reinstall classic. And about six months ago, it started shutting itself down multiple times per day. The fans would start raging and the machine would either shut down or go to sleep with no warning. This problem was solved by opening the tower and blowing the dust out of the fans and off of the heatsink. The heatsink was actually so caked in dust you couldn't even see it. Other than those issues, it has been a very reliable machine..being used between 12 and 16 hours per day since we bought it.

yea hopefully u used compressed air
and that will happen with towers
 
I have a Rev. B iMac, 17" 2.0GHz and 512 RAM bought back in August 2005 I guess it's still running well, but I would love to send this across the room to replace my mom's computer and have them buy a new iMac. The iMac sure does lag compared to my MacBook though, in all aspects.

Haha I have exactly the same computers as you and also Touch 16 GB :D

My rev.B 17" 2 GHz iMac G5 is fine, except for the DVD drive doesnt record certain DVD-Rs correctly. We have upgraded to 1.5 GB RAM from the start (bought it shortly after iSight models were released).

Since I got my MacBook I realized how s l o w my iMac is for CPU-intensive tasks O_O

I plan to upgrade it to new 20" iMac in the end of this year or early 2009.
 
Ugh! What luck!

Did you even attempt to talk with Apple Care?

No, I didn't. I had already purchased an iMac 17" Core Duo, so it wasn't my primary Mac. The Core Duo now has four vertical colored lines on the screen, so I have attached a Samsung 226BW and passed it on to my wife.

My PowerMac G4 MDD is still going strong in my classroom. Yeah, it's a WindTunnel with the "quieter" power supply, but it is a real workhorse.

At home, I'm using a new MacBook Pro, and a 23" ACD arrives tomorrow. Love my Macs, hardware hiccups notwithstanding.

oh my brothers imac goes faster than my macbook sometimes usually depends on wireless or if its wired up if its wired it will lik go way faster than my macbook which is frusterating cause mines a core duo and his is a g5 motorolla
 
The day after the first iSight iMacs were announced, I went to the local Apple store and bought a 20" Rev B G5 iMac and had the store max out the RAM to 2 GB. Machine has purred along just wonderfully over the past 2.5 years without any hassles. I installed Leopard and it took that without a whimper, continuing to perk right along. In the meantime, over the past couple of years I've added a few more Macs to the family, all intel-based machines. Until very recently I was still using my G5 each night, as it has been living in my bedroom. When I got the MacBook Air and started using that each night instead, I realized it was time to begin easing my G5 iMac into a well-deserved retirement, so it has now been moved into another room instead.

A friend has the same model, which she had bought about a month or so prior to when I got mine, and it recently began showing signs of trouble, so we took it to the Apple store Genius Bar, where it received a new power supply. Working great again now.....
 
My Mom has a G5 17-inch, 1.8 GHz (M9843LL/A) "Rev. B" iMac from 2005 that is still running strong. The power supply had to be replaced about 8 months ago, but other than that everything has been good. :p
 
I have the 1.8 20inch Powermac, the one before the built in iSight. It had the Capacitor problem as many others did: this was sorted under Warranty,and it has run perfectly ever since.
I installed 2GB of memory and just recently I downloaded and installed the hack to give me the extended desktop facility,this works well,and with the addition of a 22inch rotating screen gives Photoshop work or slide shows a whole new level of enjoyment
 
My wife's office computer is a G5 (not sure which rev), and she just recently had the power supply and logic board replaced under a service agreement paid for by her employer. Otherwise it's held up great.
 
I bought my 17-inch G5 iMac with iSight in November 2005 and it's been fine from day one until about three weeks ago when the screen developed a thin blue vertical line running through the centre of the screen.

It's outside of warranty (which is typical!) but thankfully it doesn't impinge on it's use... yet.
 
Just got off the phone with AppleCare a few hours ago, and they're sending out a technician sometime next week to replace my logic board. Hopefully that clears up my issues! It's never worked quite right.


(I love AppleCare! :p)
 
The HD in my Rev. B just developed click-o-death syndrome and failed three days ago, but I haven't had any problems apart from that, so I guess that's not too bad for 2.5 years.

I had the same problem in December. Apple shipped me a replacement hard drive under AppleCare and (fortunately) I had a backup, so I am back in business without really missing a beat. I consider myself very fortunate.

I have upgraded the RAM to 1GB and added Leopard. No problems. Computer runs great. I am thinking of replacing it in 2009 after that round of iMac upgrades. The kids are still using my G3 iMac DV, but the monitor on that one is slowly going. They might have to struggle through without a computer for awhile though....
 
I fear logic board failure

My Rev. A 1.8 is starting to exhibit weird display anomalies -- colors shifting and going out of registration, kernel panics, freezing, etc. Is this the infamous bad logic board problem? Up til now it has working working like a champ -- really my favorite iMac yet. What will a new logic board cost me?

Could possibly be bad RAM, also, but most likely, yes.... :(

Yeah, I thought it might be RAM, so I replaced it with 2 gigs of Crucial RAM (I had been planning to upgrade anyway) but symptoms persist. I really like this machine -- I think my most economical option might be to just pull the RAM and HDD and install it in a GOOD used G5.
 
There are two things that annoy me with the G5 that I failed to mention above. First, my interned connection is really spotty sometimes. During one of these periods I may have to turn Airport on and off multiple times to get it running again. It could be the location, but the MacBook and iPod touch do not have problems in this room. Second, when playing movies the iMac will make noise in the background. This is both DVD and rented movies on iTunes. Other than that, it works as well as it did back in August 2005.
