So what exactly makes the Spedo a case that stands out in a crowd Plenty. First off, it's a massive full-tower case standing a full 24 inches tall, with two massive 230mm fans, a 140mm fan and three 120mm fans. Clearly, that is a lot of cooling packed into a case making this a case aimed directly toward the enthusiast gaming community. The cooling features don't stop at a long list of fans either, as the Spedo Advance Package includes a unique air channelling system called "ATC" or "Advanced Thermal Chambers"
