I have a very similar build to this, you can find some pictures of it here:

You could probably do with a solid state drive in there, the Corsair Force 3 GT is very nice in red.
Otherwise it looks pretty decent, you could get some red cable extensions to continue the red theme. In fact you could buy mine since I'm currently in the process of sleeving my own cables. They are what is connected to my graphics card and the 24 pin ATX.
All the best,
