I thought I already posted this, but guess I just wrote it and never hit "post".
You can re-wire a VGA or parallel switchbox, a mechanical one like
this. It will provide a suitable switch as well as a housing.

I don't know if mixing return paths between the 3 outputs on the motherboard is acceptable or not, so it's quite possible that you would need to factor that into your design.
I expect that it would be. I am sure they are all just a common ground.

My first instinct would be to place the device between the receiver and the speakers, instead of the PC and the receiver, and switch the "grounds" at the same time as switching the channels
I think switching inputs is a better idea, because here you are not only going to deal with considerable current, but you will also have to switch twice as many lines (speaker returns usually are not common grounds). Also, anything shorting out here, even momentarily, could blow the amplifier.
