It will definately work for you, its a bit more involved than hash mining, take a look at www.gridcoin.us and the gridcoin reddit for assistance.
EDIT: Just check your overall temperatures, with your open frame in the picture its going to be fine Im sure, but if you have heat problems I can point you to solutions like http://efmer.com/b/
I'm not sure to be honest because it's so minimal. The GPUs are doing all of the work, you don't really have to worry about the CPU at all.
Sounds like an opportunity to mine some Gridcoin on that CPU then, and get yourself some additional payback :)
I just checked, and it was 7%. That's a great idea, I am going to look into that to see if that's possible. Thanks :)
