You'll need it. Actually, it's useful to have _2_ of them, since there
are a pair of KN11 connectors with different signals on them.

Does anyone have the full lights panel for the RK11C? It's 144 LEDs or
bulbs that display the I/O registers, etc. I have the panel, but not the
right bezel for the RK11-C (I only have the DX11 bezel...)

Not particularly useful, but the blinkenlights sure look pretty....
