I'm wanting to build an external firewire enclosure from scratch. I'm getting a bridge from http://www.fwdepot.com. Most likely this one here.

i need a power supply and was thinking about using an ATX power supply. But i know almost nothing about them. Can a switch be put on them like an old AT supply for immediate on and off. Or would that damge the drives and PS?
any help would be nice.
