It would be helpful to know the rest of the details, like CPU model, amount of RAM and it's speed,
the install device type, and boot device type, (for the actual final install). Plus any add on cards
you have installed.
Last, in general, PC or Workstation boards are not ideal for FreeNAS. They contain un-needed I/O
like PS-2 ports, sound ports, extra video ports, lack of ECC memory support and generally poor
Ethernet chipsets. In your case though, you have an Intel Gigabit Ethernet chip, so that's good.
