I'm interested in getting larger memory for my Tiger 10.4.11 iMac but I don't want to buy a new iMac or iBook. Also, I noticed that the Sims 3 is only compatible with Leopard. Would it be possible to link up a Mac mini to my iMac and install/run the Sims 3 and iLife '09 without clogging up my iMac too much? Any tips or assistance would be gratefully received.
