Corsair is going to release a new mid-tower series of computer cases, named Carbide, with two models. The 400R is scheduled to arrive on the market on 08/31/2011 at USD 100, and the 500R is scheduled to arrive on the market on 09/30/2011. They have features not usually found on mid-tower cases such as eight expansion slots. Let's see if the 400R will be a good buy.
