You already got that x4 960T black edition?
But IMO, get a nice SUGO SG08 (with an inbuild 600w PSU) http://www.silverstonetek.com/product.php?pid=317&area=
with a mini (yea intel) motherboard with usb3/sata600.
Enough juice for whatever videocard, cool and a sexy case!
I guess going small with AMD these days is just not great lately.
But if you want a shuttle, better get an intel version?
Sure you could get that SA76R4 but if you buy a new computer, it feels like buying and old 1 (no usb3/sata 600 for example) and I'm not sure if that 250w is enough.
