Connect the CAT5 cable from the sender's 'U' output to the receiver card's 'A' input.
Connect power to the cube power busses with the ATX supply.

Before turning the power supply on, make sure all power is wired correctly. Seriously! This is 30A of 5V power, so you really really want to make sure its wired correctly.
Once everything is powered on, your computer should detect an external display. Adafruit receivers/senders are pre-programmed for the 16x32 RGB LED panels, so make sure you configure them with the files from this tutorial. If you can 'mirror' your display that is easiest to debug.
If all is working properly you should see something like this!

Once everything is verified working, turn off the power supply and screw in the top and bottom panels using the pilot holes from earlier. In order to have the image displayed on the cube mirror the diagram below, the bottom panel's vertical arrows should be pointing to the bottom of the first input in the horizontal chain, and the arrows on that pointing to the 'bottom' of the top panel. Essentially creating a seamless 3 panel side, just folded onto itself.
The data flow for the LED panels works the same way as the Video Wall, just with the rows folded in on each other. The 6 sided cube mirrors from 3 rows on the video input, when unfolded it looks like this:
If you want to start playing around with tiling images, check out the ZIP below, with Processing code and example images that look good on the flattened, 6-sided video cube
When screwing in the bottom side, leave off one corner and feed the power and data cable through the seam. The panels will flex enough to let them through.
