If there are two gtx 570 dc ii's:

On a Gigabyte z68x-ud7-b3 motherboard, in slots PCIe16_1 and PCIe8_2:

Will the headers for front panel connections be blocked, or will there be enough flex in the cables to wrap underneath?
EDIT: If anyone else comes to this question trying to SLI triple slot cards, the only mobo I have come across with full clearance for two triple width cards and a slot between them for airflow is the ASUS P8P67 WS Revolution
EDIT 2: System arrived, and guess what? They clear the headers, just, although I doubt they would clear the usb3 headers as the cable is sturdier.
