Core i3-2100 with 65W power supply?

Even though the last part is a shopping recommendation (for a better case) there is still a valid question in there, the PSU requirements: Based on this PSU calculator you need a minimum of 126W. This is a rough estimate based on the info you gave and I'm sure you can get away with less depending on your cpu utilization. But I would definitely put a slightly more powerful supply. In fact if I take the Blu-ray drive, the ssd, the hdd, and the RAM out of the picture it still says a minimum of 83 watts.

That's AWFULLY low wattage. I know those are low power components, but even without looking up the parts and figuring the expected usage on this machine I think that's way too low - even if it works you have no overhead (and running power supplies at high usage kills their lifespan). I would recommend no less than 250-300W even for an extremely low power machine like this.

(Shopping recommendations are offtopic and so I haven't addressed that specifically; I actually recommend you edit that out of your question or it's at risk of closure.)
