OK - Just received my HP E-PC40, and there ain't no way I can see how to add an Opus type system. I wanted to buy one, but the motherboard on this HP doesn't look like anything on the diagrams.

After opening it up, I don't even see where to connect anything for the on/off switch. So, I'm looking for a pre-made, "easy" to install remote switch.

OR, I live in the Los Angeles area. Anyone interested in installing an Opus system to my E-PC 40 for a small fee? I have the battery and ignition switch wires all ready to go - but I don't think I can screw around with this HP unit.
