What do do?

[HelioX]

I have the following parts available to me.

1055T 125W
MSI 890GXM-G65 mATX
x2 2GB Corsair XMS3 DDR3
x2 2GB Corsair Dominator DDR3
x4 WD500AAAKS Blue's
Corsair HX650
Corsair H50
XFX 5670
Random fans and case accessories

What would be the best storage use for this combination of parts? I would like to maybe build a freeNAS box or maybe a WHS with it for streaming to WD LiveTV player. At most I am looking to spend 300-400 US on other parts with the stuff I already have.

Would I be better off with an Atom or i3 maybe?

Edit: Sorry for thread topic typo, lol.

If I was you I would trade the x6 procesor for an AM3 X2 + 8GB of DDR3.
