Can I use PCI express extension cable? Board is only 10.5 wide..Chassis should have some expansion slots outside of the board.
OOOOOH one of those issuesMake sure you get a PCIe 2.0 compatible cable (or better, a 3.0 compatible one for future applications). Most of the easy to find flex risers you find on eBay or Amazon Marketplace are 1.0 only designs. If you use a 1.0/1.1 cable with the M1015 you'll be chasing ghosts and performance issues for a long, long time before you track it back to the silly PCIe flex riser cable.
