No current 5870 is 9 inches long. Check your facts or you'll find yourself buying a new case. I think you're talking about the 5850... and if that is the case, then yes... those 2 power connectors are on the end. For me those two cables just extended into my drive cage... nothing major. A 5850 should fit in MOST any mid-size case... the 5870? Some mids will accommodate it, but a lot won't. My CoolerMaster Scout would not have held a 5870 without some "modifications" I opted for the 5850... that was plenty for my needs.
You've been warned.
