The card takes up three slots and measures 13 inch x 6.2 inch x 2.5 inch, which means it will only fit in large Extended ATX cases or open-air setups. This complicates multi-card SLi and restricts air flow on some motherboards (ASUS provides a 12cm SLI bridge).

The dual 120mm fans that we see on the Mars II is the largest air cooling design we have ever encountered in a retail graphics card. They push a lot of air at high RPMs and were generally silent in normal operation.
