The Power Supply unit is one of the most important purchases you can make. The Case+PSU you linked has a complaint about the PSU blowing up.
I highly recommend you purchase a case that you can use for many years, and separately purchase a power supply unit that is highly rated. A bad PSU can shorten the life of all your other components. Read power supply reviews at
