Motherboard Question

Hello guys I am planning on doing a 3 way sli and I am wondering if I will be able to do it on this board (have space between pci lanes) thanks in advance for all the answers

Motherboard: MSI Big Bang-XPower LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E16813130289)

3x MSI N580GTX Lightning Xtreme Edition GeForce GTX 580 (Fermi) 3072MB
(http://www.newegg.com/Product/Product.aspx?Item=N82E16814127589)

I have a white edition of Corsair 600T case

I am just concerned that I won't have space to do 3x sli on the board, can someone confirm this?

6 x PCI Express 2.0 slots
PCI_E2 & PCI_E5 support up to PCIE x16 speed
PCI_E4 & PCI_E6 support up to PCIE x8 speed
PCI_E3 & PCI_E7 support up to PCIE x4 speed

count the slots and see if there cramped......i like that board also...

The Big Bang Xpower is more than capable of supporting tri-SLI, and can support quad-Crossfire. It's just your cards might run hotter due to being starved for air.

I have the same board and it's awesome (once I managed to get it up and running). Overclocked my 920 to 4.2 right away.
