I'm looking for a low cost file server to replace all of my PCs. This file server will house 4 or 5 ATA drives (I am aware I'll need an ATA PCI card). I would also like this machine to run Tiger comfortably. The programs I will run on this computer will be safari and adium, maybe a few other programs, nothing intensive. My question is, will a B&W G3 (350Mhz) be enough, or a low end G4 be better. Either machine will have at least 512MB of ram. If Tiger is too much for these machines then Panther will suffice. Thanks for your advice.
