So this is my computer. I would like to install OSX on it but not on his HD. I got a usb adapter that convert my old 20 go IDE HD into a usb HardDrive. I succesfully install IDENEB 1.3 but I can't get to make it work. I got many error like AppleIntelCpuPowerManagement, ApplePCIConfigurator, ApplceACPIPlatform and finaly pcGenUSBEHCI.

So would like to know which OSX will be the most compatible with my computer and if I need to patch something. Thx Alot for any help or information.
