You can make one for about $2 and a few pieces of wire. Get a momentary pushbutton switch (mini) from Radio Shack, solder two wires on it. Find (from an old MB etc) a two pin lead that will fit on the ATX soft switch on the MB, preferably one that has at least 2 inches of wire on it and connect it (either solder or twist together) the leads from the switch. Now, drill a small hole in the case somewhere, (I have even put this switch on the back of the computer), and mount the switch. Once it is mounted connect to the MB softswitch and viola', you have an ATX soft switch. Not hard to do, I have done this several times!!
