Well hello, I'm about to upgrade my trusty PowerMac G4 Dual 450 (Gigabit Ethernet) to a worthwhile storage system. At the minute, she sports a rather dismal 80GB startup. As this is a fairly old G4, it requires a PCI SATA upgrade to control drives larger than 120GB. I would like to go for the Sonnet Tempo card here, http://www.macheaven.co.uk/?page=proddetail&prod=1362 and 2x Seagate 7200 SATA II 500GB drives here, http://www.ebuyer.com/UK/product/97633 Does anyone have any recommendations, advice or even objections to my choice of purchase? I would love some input. Thanks in advance. Rich.
