I ended up changing the power entry module from what you see in the picture above.
I'm using Corcom PSJS0SBX0
(Warning PDF). It doesn't have an EMI filter, but it has a switch and fusebox. I figured that I didn't need an EMI filter since my 12V power supply has one included. It was pretty much the only thing available at my local electronics store that met my requirements.
You can take a better look at the pictures I posted on post #141 earlier. It's the big plastic box on the back right corner.
