Im looking for a mid-tower case to get for a computer I'm building, but I'm having trouble finding the right one. The biggest issue is finding one that will fit a Radeon HD 6950 GPU, which is about 11 to 11.5 inches long. The mobo is a standard ATX and I only have one HDD. I'm looking for something with decent ventilation, and preferably some sound dampening. As far as budget, I'm hoping to spend $50 or less, but I'm a little flexible in terms of price.
