Amazing! I just completed the entire install, configuration, set-up and finally everything seems to be working on my Mac as it should, but nothing in life is perfect and here we go.
Take important notice of this!!!
When I installed Leopard I chose the default file system (HSFX) which means the HDD will be case sensitive, meaning you can have test.jpg and test.JPG in the same folder and the OS will handle them as different files, which is just what I need for my developing work. However Adobe does not support this format.
I went on to install the CS3 package and got an interesting notice:

After doing some research I found out that Adobe just does not support this file system in their installations since it’s apparently inconceivable that anyone would ever need case-sensitivity as the default file system, so they choose not to support it… I would say they could easily publish that case-sensitive file systems are not supported in the package system requirements or perhaps include anything in the FAQ or general support sections.
Getting CS3 to work would take a reformat and reinstall of my system drive since they use some of the built in frameworks and the system needs to know where to find them.
Never mind that thousands of third-party developers seem to be able to write applications that both leverage system frameworks and work without a hitch on my “unsupported” file system.
Be wise, take a look at this before upgrading to Leopard:
