@ -jB - pickup a bag of cable ties (black and possibly red) and get to work with all the bundles of wire. you can try to hide some more wires under the mobo and the mobo tray.
don't be offended but for a first time builder thas good, but you can do better. and about the lights - try to have them in contrast - e'g the majority of lights are red/orange. Pick up some white led fans and use them in place of the top fan. For a moment there, i thought that blue light was coming form the top fan - actually a blue led from the mobo.
maybe an enermax white led fan to replace the fan of the coolermaster hyper 212+ fan.
I think that blue object behind the rig at night is your monitor?
