i went thru the circuit and it'll work. but i haf one doubt regarding the relay. in that circuit the relay will remain on for the entire period till the circuit is manually switched off. when connected to the computer this means that the two pins will be shorted untill its turned off. however the method applied to power on modern system is that there's a momentary short of the two pins on the mobo. as soon as it powers on the switch is released and they are no longer shorted. will there be any harm to the system if the two pins are shorted for long? that is my question now.
