I've got the motherboard power extender plugged in, the 3-wire power line 
running off of that plugged into the VFD.  I've also got the 2-wire power 
switch inlined to the motherboard header.

I can actually power up the box using the iMon remote that came with it.  And 
off if I'm lucky enough to press the button just long enough.

Hmmm, I've never seen a single photon come out of it.  Do you get some output 
on yours even if it's not connected via the USB?

I think that would confirm a dead VFD, or dodgy power connection I suppose.
