Sorry didn't see this until now, and it still doesn't work. I remember the first time I tried turning it on there was a green LED that came on for about half a second until everything died.

How difficult did the repair turn out? The hardest thing I've done was repair an iPhone screen lol.
It's not bad but as in any endeavor, lots of planning and research is always great to give you a heads up in exactly what the process will look like and how you will achieve it. - Ifixit tutorials, youtube & powerbook medic videos are worth their weight in gold to any first-time break downs. Anyhow, to do the job, you need to remove the CPU and heatsinks, then you can tackle the PSU. There is plenty of handy DIY step-by-step videos and ifixit literature on removing the CPUs and PSU. Just give yourself PLENTY of space (on top of a big table is perfect) and plan how you will take your parts out and where your parts will go and their screws. I like to use a ice cube tray to hold my screws but if you are worried about losing them, a $5 magnetic bowl from harbor freight is a cheap tool that will keep all your bits in one place. For the heatsinks and cpu, you will need a few special screwdrivers, so pay attention to the tool recommendations on the ifixit guides because without them, you'll get stuck half way through the job and shopping for tools isnt exactly easy with all the covid19 lockdown BS going on, so again be sure that you know exactly what tools you'll need and if you dont have them, buy some off ebay or whatever and have them shipped to your door before you start the job.
Consider that if you take the time to remove the cpus, that you also remove the logic board (again plenty of videos and step by step lit online for this task) using this opportunity to clean and repaste both the CPUs and the Northbridge chip on the back side of the logic board. These things are 10+ years old now and these PMG5s get HOT, so replacing that old nasty thermal grease is a great thing to do and a fun project. It took me about an hour to teardown, clean, repast and reassemble my a1047 but wow what a fun project as it really gets you intimate knowledge and understanding of the guts & engineering behind your powermac.
Best of luck to you.
