Budget - Budget NAS

Looking to build a VERY low budget NAS - any opinions on this? I've already purchased these items, so I'm hoping there are no glaring holes here. This is only my second build. I have $115 in this so far. Still need to get a couple of HDD's - looking for a good deal on those. I will be running FreeNAS from a USB stick, therefore the USB MOBO cable.
