Hiper PSUs are OK - that'll be fine.
I would recommend getting an Arctic Cooling Freezer 64 over that Zalman cooler, as it's just as good and comes with the thermal paste as well I believe
I doubt you'll need a UPS - just save reguarly
On the fans - I believe that the back fan slot can take a 120mm fan, after reading some reviews, so I would recommend getting a fan (such as a Sharkoon 2000 series) to replace it, as it will be quieter and provide better cooling (especially the Sharkoon one). "The rear of the case is a standard layout. The case comes pre-installed with an 80mm blue-led fan, but has the capability to mount up to a 120mm fan."
