> Are there different versions of 10.5.8? Yes and no. When using the retail version, you’re good. Once installed, you’re good too. The only thing that may not work is using a gray installation disc from an Intel-based Mac and trying to freshly install from it on a PowerPC- based Mac. The one and only reason: the kernel for the installer may be Intel- only. The installation itself is universal thou. > Are most SATA hard drives compatible with the G5 Quad Core? All SATA drives will work. Even SATA 6 GB/s (also sometimes falsely called SATA-III), the newest SATA revision, work. > For example, when you read earlier Specs about the G5, it says you can > install "up to a 500GB" SATA drive. I'm guessing that was the largest > one available at the time ... 1TB+ now should be ok? Yes. That’s the only reason. Up to 2 TB will work. Why is that? Because the partitioning scheme used on Power Macs is the Apple Parition Map (APM). Its limit is 2 TB due to 512 blocks and 32 bits used for addressing. Theoretically you could set the blocks used to 4k (4096), because that’s also what modern HDDs use internally. Then you should have a limit of 8 TB for the HDD, but I truely doupt that Mac OS X can handle that (because it’s non standard). And, how would you do it anyway? http://en.wikipedia.org/wiki/Apple_Partition_Map That said, if you use a > 2 TB HDD, Mac OS X will still be able to use that drive. It will simply only use the first 2 TB and ignore the rest. What a waste!
