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.
