I currently own an iMac (see signature) for backup use etc. However, I do find it quite slow for use and it is now no longer compatible with the latest OS. It runs leopard. Therefore, I am thinking of upgrading my backup machine to probably an eMac 1GHz G4 and running leopard on there. How adequate is the 1GHz/Radeon 7500 for running leopard? Is the transparency and ripple effects the only things I will lose? I quite like the 3D dock and would like to keep that. Will the basic DVD-player features work? I am thinking of equipping the eMac with 1GB of RAM. Also, would it be worthwhile to go for the 1.25GHz version. I would really have liked the 1.42GHz version with the Radeon 9600 but I can't get hold of that anywhere theyre so rare!!
