Bitfenix Prodigy Build And H60 Placement!

You can definitely do that airflow setup, however unless you modify the ODD bay you really won't get much airflow from the top-front fan. Also, the stock fan on the H60 can be loud, I was using it for a while and it made a loud high pitch buzz. If I were you I would move the H60 RAD to the back-top and use the fans you were going to use in the top and run a push-pull system. Then put a 140 mm fan for exhuast in the back.

Newegg has this 140mm for cheap and it's very good.

My fan setup was just like the one you plan, then I decided to go with a push-pull and to make it fit had to move the radiator to the top-back placement. Doing this dropped my temps by about 5°C.

As far as PSU's go, don't go cheap here. I went with an Enermax originally and it blew on me and smoked and made me worry for a week as to whether or not my other components were fine. Luckily they were. I recently switched to Seasonic as recommended by most on this site and love it. Here's the exact model I have. I had no problem fitting it in the PSU cage.

According to benchmarks and a few members on this site, the 670 really isn't worth the money, Newegg right now has the EVGA 660Ti Superclocked+ 3GB for $290 after $30 MIR. That's a much better deal than dropping $390 for a 670.

Everything else looks pretty good!
