We mainly know Gigabyte for their motherboards and video cards, but they do make cases as well. Today they have released their IF 400 Mid Tower Case, which is made for gaming builds. The case has room for five hard drives (3.5-inch or 2.5-inch) and two optical drives. You have cooling in the form of two 120mm fans (intake and exhaust) and room for 2 120mm fans on the side panel and one on the bottom of the case, but they are not included.
The case is made of SGCC steel and ABS. It also does have USB 3.0 support. No word on pricing yet from Gigabyte.
