Nice build, good work.
I also like Steve's LED's but I do have a few small complaints 

  He originally didn't use solderless LED's and that makes ones life so much easier.  And he also uses cheap knock offs for power supplies which I've replaced 2 already due to faulty fans.  Before I powered on my last replacement I learned and swapped the fan first - lol.  I actually have one of his retro kits on one 29 cube and the other is using Rapid's.
Never the less, everything looks really nice.  Thanks for sharing!
