Dear god, another Prodigy when trying to go small? You do realise it's bigger than some Micro ATX cases, yeah?
Either dump the Prodigy and put it in a Sugo SG05-450 or go to Micro ATX and put everything in a TJ-08 - yes, it's smaller than the Prodigy.
If you go SG05, mount the H80 vertically to fit, but you'll have to locate your 2.5" drives elsewhere (flip the PSU upside down and stick an Akasa dual 2.5" mount to the underside). You'll also have to run an optical drive externally.
The 450W PSU is great - extreme bods are running a GTX680 off it with no hassles.
