After lots and lots and lots of wiring I have all the LEDs working.  I decided to get fancy and do everything with molex connectors so stuff can be removed/replaced easily.  But it looks a bit like wiring spaghetti right now.  I'll clean it up as I mount it all in the housing.  Here's the drivers and wiring and all the LEDS wired up:
And here it all is fired up.  
Still need to mount optics, pick up some fans and I'm waiting for the Arduino parts which should arrive this week and I can figure out the controller.
