Looks great man, that last shot is great. It needs a focal point though. Even if everything is in focus(High App), it's hard to see anything. With all the colors and wire, in addition to graphics card being directly in the middle, it leads our (mine at least) eyes directly to the back of that graphics card. I'm no pro photographer, but am only telling you what I would do Hope that helps?

Enjoy the Rig man.
