I am thinking about buying the G5 Jive and the Tempo E4I PCI Express card...I already have 2 x 500GB hd's in my Powermac so I was thinking about buying the kit and when the prices come down pick up 3 more 500GB hd's. My only concern is that it will cost me $240 just for the Jive and the card with out any hard drive...is it worth buying or are there any other solutions out there any cheaper?
