Does just about everything I need it to do , and the Mrs can play her Lego Batman on it too
As you can tell cable management wasn't a strong point in this build
although there is still really good airflow in the case. Everything justs gets dragged out of the side by the 2 x 120mm fans which are barely audible on the lowest settings.
