Got PowerMac G5 for free (without hard disk but I had one spare). Very well preserved externally but very much dust inside. Apparently it has never been cleaned or if it has, probably rarely. At first the machine would not chime but it did display picture, booted from Leopard disc (scratched) but the machine hung. Second attempt got me to installation process but installer failed because it couldn't find something. This might very well be because the disc is so scratched. After this first somewhat succesful booting attempt the machine suddenly started to chime but failed in installation again. Previous owner said that there has been problems with the machine so I expect that there are, but so far I have small amount of hope that the problem could be cured by simple tricks. I do know that motherboards fail very often on these.. So far I have removed almost all RAM, reset SMU and I took the battery out for a while. It would awesome if I could make this work, this would be tje fastest PPC Mac I have ever owned and for amazing price I will try inspect more tomorrow. Edit: this has two CPU's and Radeon 9600, uses DDR400 RAM.
