I only see 2 Sata data headers (labeled #6 & #11) So you cannot split Sata data cables, but you can Y split Sata power cables. I don't see an IDE header on the MB so that leaves out a IDE to Sata conversion board. The one you posted is a USB connection adapter. It will work, but not the best for permanent installation. You might be better off with a Two (2) drive Sata HD DOCK.
Most ext DOCKS will work with Desktop & Laptop Sata HD's
