Leaking capacitors in my iMac G5

Well well well.... It looks like I have been forever cursed with these damned f*ing "industrial espionage" capacitors.
Yes, my beloved iMac has been freaking out the last couple of days. Video corruption, hard freezes, you name it.
Finally it gave up the ghost today. It froze and then wouldn't reboot. Every time I turned it on, the video was totally corrupt and it would hard freeze just seconds after reaching the desktop.
So I opened the thing up.
Imagine my shock, chagrin, and surprise when I found bulging, leaking capacitors on my IMAC :shakehead
I thought I had seen the last of these bastards with all my KT7s and Soyo Dragons and other motherboards I've RMAed over the years with these damned capacitors.
Sure enough, I started googling, and it looks like MANY people are having the same problem.

You know though, it would seem like Mac would have learned from the PC industry about using those cheap counterfeit crap caps. :shakehead It's not like this problem is just surfacing either (the bad cap problem). :shakehead Even EPoX has upgraded their caps to decent ones now.
Sorry to hear it happening to you, prime. At least it's still under warrantee though.
For those of you who missed the story originally:

Maybe so, but those boards were produced years ago and not present production like your imac. :shakehead
Sorry to hear it Prime.
You mean ahead of course.
When you walk backwards, everyone seems to be behind you. If you slow down they fall farther behind...
Sucks prime, hope Apple clears this up for you on a machine thats only 4 months old. I also had some bad cap problems with a Gigabyte board, so no mac-bashing from me, nothing they can do about it.... as long as they rectify this issue for you in a timely manner at no cost to you.
Yeah thats what I was going to mention. I know you have been around a lot of PCs, good chance more PCs than Macs.
And still having bad caps after what has happened in the PC market is the bad thing.

Now, we get to see how long it takes apple to send out a new "midboard" :shakehead
And in case anyone cares...
C = E*A/d
A = overlapping area
d = distance between the plates
E = permittivity of the dielectric
however - this neglects fringing capacitance...but who really cares about that...or anything I just wrote.
