Aren't they a bitch to replace. From what I see its somewhere in the lower bay of the case. I'd imagine it would require stripping most of the tower, or does the PSU compartment slide out without having to haul the CPU assembly out?

Yeah. I think you have to remove pretty much everything to get to it. All video/pci cards and the entire logic board, unhooking all cables.
The power supply is located lengthwise along the very bottom of the G5 case.
 
Or Apple is taking a feckin long time with it. This seems to be the normal for getting things fixed is it not? 4 - 5 days. Though I've heard some as long as 10 days.

Good lord- I hope that never happens to mine. I've got a dual core 2.0. I would probably melt down if that happened. ;)

No... you don't have to remove the logic board. You do have to remove:

- CPU fan assembly
- CPU cooling assembly covers (just the thing that says G5)
- CPU(s)
- Metal plate covering power supply

Then you remove two screws on the bottom of the G5 holding the power supply in place. Unplug the power from the board, and pull it out.

It's not too bad at all... like 10 - 15 screws.

Wait.. let me qualify that last statement... it's always a bitch the first time.

Yes yes, that isn't the liquid cooled or Dual Core G5, but it looks like the same rules apply on how to take it apart.

That water cooling unit also looks a blast to work with! http://homepage.mac.com/thunderaudio/PhotoAlbum11.html
 
As someone who just replaced a power supply (and that being my first time inside a mac), I've gotta tell you that it is a bitch to do. Removing the heatsinks requires a really long allen wrench (luckily a plumber was working in the next room and we were able to borrow his), and a lot of plastic parts that are like chinese puzzles when it comes to removing.

And reconnecting the cable that's closest to the front when you've put a new P/S in, is painful. Literally painful.

And finally, don't forget to hit the PMU reset after you've installed!
 
Right! About time that I gave you all an update of what happened!
After talking to an Apple technician, we were pretty sure that it was the PSU that blew.
Unfortunately, Apple said there was nothing they could do, and because I hadn't bought a 3 year Apple Care protection plan at the time of purchase it looked like I was going to have to pay for any repair, costing me between £250 - £280 (£150 for the part and roughly £100 for the repair itself).

I was about to bite the bullet, however, just before I left home to take it to the repair shop I thought I'd just check the ins-and-outs of an Apple warranty etc. online.
It's a good job I did, because I found out that something that may be useful to a few of you out there!

If you purchase a computer through the Apple education store (which I did), your machine comes with a "special three year parts and labour coverage, with additional first-year warranty and support benefits, as standard".

Awesome.
So, I rang Apple support again just to check this out. They confirmed that this was indeed the case (although they had neglected to tell me this originally), and all I had to do was take it to a repair centre and they would take care of the rest! :D

Woohoo! A happy ending!
 
Nice. Will Cheyney, has your PSU ever made any buzzing sounds at all, certain periods of the night. Previous or new. As I'm also on a Dual 2.7 which mine makes these like interference buzzing like from a dimmer switch or something like that... It only happens certain times at night when the lights are on.
 
I've noticed no noises before. However, just before it went 'BANG' it did make quite loud buzzing sounds - just like that of a dimmer switch :(
 
my dual 2.7 g5 has just sprung a leak, its only reading all these forums that made me check the machine before it went bang

coolant below the cooling system on top of the power supply, what a rubbish design of a system !

anyhow good luck people with all these problems lets hope apple just does an repair scheme on liquid g5s eh ?

regards
