It works wonderfully. Being modular was wonderful and it being SLI/CrossFire ready meant the cables for the GPU have two 6+2s on the same wire, saving you time and space, downside if you are not using those, you have a lot of extra wire hanging about.
Comes with exactly what you need and nothing more.
Also has a nice bag to store what you don't need/not using at the time, so you don't just lose everything, can put other not used screws and zipties in there as well!
