The computer is ten years old and still has a bright screen and I recently upgraded the memory to the maximum available. In other words, other than being a bit slow it was in perfect working order and was the computer used in the shop so I needed to replace it or fix it. I gambled and won...for $150 I have a new G5! That is better than $1000 for a new one.
The instructions were perfect. They described the pertinent necessary steps exactly! It took a couple hours since this was the 'difficult' G5
Fix you Mac! They will run forever.
