Description
The layout of the GF9300-D-E is similar to the DG41MJ. The board has two internal SATA ports which are located near the bottom-middle of the board. An additional eSATA port can be found on the rear I/O. Moving the third SATA port to the rear I/O is a good decision since it allows for easy storage expansion through the use of external drives. It's unlikely that you'll miss having the third SATA port internally since many ITX chassis only have enough space for a drive or two.
