My friend has a phantom. It is a neat case, but to be perfectly honest most builds make the case look very empty and barren, somewhat unnatractive. It has plenty of 200mm fan slots which offer great airflow, however keep in mind if you are after different kinds of LED fans, water cooling, silent fans, you want cases that use 120 and 140mm fans, as these are the sizes all those things generally come in. The build quality of both is fairly equal, I haven't examined the phantom up close, however I can say the build quality of my 500r is very nice. Corsair is well known for their quality builds and great customer service, if those concern you, I would lean towards the 500r. While the phantom looks good, there is a lot of plastic on it. I considered getting it but the whole front and top are large plastic shapes, I move my computer around a lot and they could be easily dented or broken. Those parts will fit fine and as far as cable management is concerned I can tell you the 500r is much more satisfactory. There is very little cable management room at the back of the phantom, my friends side panel is permanently bent outwards a little as a result of cables being unable to fit in the given space.
