I will be building soon, and want to know if a Challenger U3 (USB 3.0) or Rosewill Blackhawk would be a better option. The Blackhawk comes with more fans, and is a larger case. I don't need the 6 front USB ports however, as that is too much. I would overclock the i5 3570k a little, as well as want room for larger GPUs. Which would be a better fit for my needs?
