The build is interesting, all the options being mentioned are neat...just a matter of getting a majority vote to single things out.
About the spacers, considering there are a few sports fans on the forum, what about spacers honoring the World Series champions?
Not that I am a fan of any particular team, just thinking that something might be done to along a line set this build apart.
This website describes their colors:
