The only thing that worries me is the 3.5" drive. Do you know the current requirements of the drive you will be using? Have you already powered the system from the Morex? If so, the P1280 should work fine.I have a Cubid 2699 case (60w morex ??) with a slim cd drive and 3.5" HDD.
You could either power it from the Secondary Output of the P1280 (it's cabapble of at least 3+ amps), or you could add the CNX-P5V regulator that's coming out in June. It will give you an additional 3 amps for your firewire devices assuming they are on a powerable hub.I still don't have power to the firewire drive though... Suggestions
