[asterisk-users] No-mobo PC for USB Drives Enclosure?

[Nick Silvestro]

CAUTION: doing this could be bad, i take no responsibility etc etc

Put a paper clip (or any join) between the green wire and any of the 
black wires on an ATX power supply main lead to power it up without a 
motherboard - google "power up atx supply without motherboard" if you 
don't trust me

Enjoy!
