Do you mean the Corsair 4000D? If so, I'll just ignore the amazon review nitpicks and go with this case, since everyone here seems to be quite positive towards it.
They aren't all winners in the configurator but none of the regulars will ever recommend a poor case. We all have our favourites with aesthetics in mind but performance wise you'll always be guided in the right direction.
As suggested, take anything written on Amazon with a large pinch of salt. The information can be taken on board, but always have it sanitised and clarified.
The 4000D is absolutely one of the best cases on the market. If you wanted to spend a little more, and have a tangible difference, the Meshify 2 Compact would be my next choice.
