I made a very similar build almost 2 years ago.
I did not like the Jonsbo N4. The HDD temps were bad. The case amplified HDD noise and was a pain to build in. I used a Silverstone SFX power supply. I had two of those PSUs fail in less than a year.
After the second expensive SFX PSU failed, I decided I did not want to buy another. I changed cases to the Fractal Design Node 804 and bought an inexpensive ATX PSU. I have been much happier with my build after those changes. My HDD temps dropped by about 10 degrees Fahrenheit. The case is much quieter and I was impressed by the quality.
