Lian Li Modular Cube Case
 

There are just a few cube cases on the market, and this one is spectacular. The overall build quality, construction, features, accessories, drive bays (18 x 5.25"), air circulation (3 optional 120mm & 2 optional 80mm fans), the different compartments, and so on, makes this an exceptional product. The only thing that this case is missing is a removable motherboard tray. Overall though, it's an unbelievable all aluminum cube case!
