I considered this originally, but the speakers are the only accessory that i need this for, so i cant really justify the added expense. Plus i already have a bunch of relays so i might as well build it myself, for free.

Also the speakers are already being hacked/de-cased with a new potentiometer and some 4" auto speakers so it doesnt bother me to add another modification while i'm at it 

JustMichael:
Do you turn on the pc and monitor separately then?

Blanka:
How are the speakers powered?
If it is having some simple 12V rail powered digital amplifier chip inside, you can feed that from the PC powersupply instead from the built in AC converter.

I just leave the monitor on all the time, i'm aware that it still draws current when in standby but this doesnt really bother me.

This is another option i suppose, except the amp is inside the sub enclosure, which i don't intend on modifying.


Anyway ive been looking up on the smart strips, i didnt realize how cheap they are. So maybe i will just get one. However i cant seem to find a 240V version with australian sockets. Does anyone know where to find one?

wweumina:
Bunnings and Officeworks both have powerboards with master and slave sockets.  Usually go for about $55 aus.
