Foxconn DigitaLife ELA motherboard review

The expansion slot configuration is where the ELA gets really interesting - Aside from two PCI and two PCI Express 1x slots, this motherboard also offers up no less than three electrical PCI Express 16x slots. We've already covered that a standard P45 chipset motherboard can be equipped with two PCI Express 16x slots which both have eight lanes of bandwidth in a CrossFire configuration (with the full sixteen lanes of bandwidth available when using a single graphics board), so how have Foxconn managed to squeeze a third graphics board slot into this offering?
