what does SFF mean? small form factor?
If you want to stay true to your SFF theme then the CM 130 has the dimensions almost half the size of the BitFenix Prodigy. Sure, the cooling on the CM 130 isn't as effective as the Prodigy but its good enough for most mainstream overclocking and is a true mini-ITX instead of a mirco-ITX sized case housing mini-ITX found with the Prodigy.
