How about turning all this on its head. If you're looking at a Prodigy build, which frankly is so big it defeats the point of "small form factor", then why don't you consider a Silverstone Temjin TJ-08E?
It's the same size as a Prodigy but supports Micro ATX boards, which instantly opens up the playing field. No more Mini ITX premiums so boards are a bit cheaper and more plentiful, plus you have the AMD option too (although why would you want to I don't know).
