In-Win brought a new case to CES this year called the S-frame and painted it in a sleek black and gold. The case is just one sheet of 4mm thick aluminum that is bent in order to achieve the design. A sheet of tempered glass is used as the window of the case, and because this is an open air case, there is no real bottom or top. The interesting part of the design is that the mounting pattern for the motherboard is rotated by 90 degrees counter clockwise. However if you are one worried about dust they were also displaying their S-Box case which also for the most part is made from one sheet of 4mm thick aluminum.
This case has covers for the top and bottom along with tempered glass for the window. Another interesting product on display was the earphone holder which could be suctioned to just about any hard surface - including a computer case.
