Need Help, just built a $2,000 dollar PC and it looks messy any Advice on this or should I leave it?

I'm kinda new at this, but need help making it more neat. Any Ideas To This Build? (Black, White, Blue) Theme... Need help getting my build straight cause I think its kinda messy ( I don't know), but if you guys have anything you guys want me to add into my build like a new CPU Cooler (Liquid Cooling Pref) then tell me, and if I need a new video card or even an additional memory card anything guys, i'm only 16 and this is my first time building one of these so if you guys could help me make it more nicer and you guys think that it will all fits then please message me back cause I don't know what i'm doing lol, but if you guys think that my build is good then tell me. Because I don't think this build is worth the $2,000 dollars i'm spending, so if you guys can help me make this PC worth the $2,000 dollars i'm spending that would be a miracle. Anyway Thanks Guys 4 all your help!

Price Range: $2,000 - 2,500 Link of the Build: http://pcpartpicker.com/p/VLBf6h
