Why the Prodigy? It's huge for a Mini ITX case and you're not putting anything in that will use the space.
I'd personally go with a Silverstone SG05-450 for a cute dinky rig - will still fit the GTX670 suggested above and the 450W PSU bundled is a great unit.
I personally went for the Prodigy because I just really don't like the looks of the cuboid design that pretty much all other ITX cases use. It also fits nicely under my TV next to my drawers
