I plan to build a gaming PC/HTPC this summer after Intel releases Haswell. I have no intention to overclock and am going to use an Antec 1200V3 case. I will be using two 7200 rpm 3TB Seagate Barracudas and a 256 GB Crucial SSD. Do I need hard drive cooling?
It looks like your case has plenty of fans to cool your hdds, I would make sure you place the 2 hdds several bays apart to ensure they get the best cooling.
