I help a small nonprofit (read tight budget!) with an all Mac network of 2 G3 iMacs, 1 intel iMac, 1 Mac mini, and 2 eMacs. All are using OS X (10.3.9 & 10.4.11) The mini is used for file sharing and one of the eMacs is used as the dedicated database (Filemaker) server. The db server eMac is now giving a kernel panic every restart and the db is giving intermittent problems. It is time to replace this emac. My question: What suggestions do you have (on a tight budget) for a replacement? A new Mac mini? A used G4/G5 tower? other?
