You're going to need a video card to operate it. FM1 sockets are really strange, and let the processor have video controlling capabilities. The processor you have chosen does not have video capabilities despite being a socket FM1, so you will need to have a video card to set it up unless you get
this one. It adds about $30 to the cost, but lets you not have to buy a video card. Second, since you're only hosting Minecraft, the HDD won't bottleneck stuff. It would make more sense to have the OS on the SSD, but this is just me being me. Third, the HDD you've selected isn't very high quality. It may die before or after 3 months or more of operation.
Other than that you could turn this into a gaming computer when you're done with it by purchasing a high-end video card and a new power supply.
