Well... Not really.
-750w is overkill for a power supply. It's not really an issue, but you could spend less without noticing a difference on a 550w gold rated PSU or 650w gold rated PSU.
-You don't need 16GB of RAM at all, it's overkill. 8GB is fine for any games.
-The processor you chose is an APU, meaning it has integrated graphics that drive the price up. Get an Athlon X4 760K instead; it's basically the same processor but for $80 instead of $130, and you won't notice the difference because you're getting a graphics card and therefore won't use integrated graphics.
-Your motherboard will not work with the processor you chose, or with the one I recommended. You'll need a motherboard with the FM2+ socket.
-The HDD isn't bad, but it is overpriced considering it's 5400rpm.
-No reason for a water cooler in a starter PC.
Also, just so you know, I have the gunmetal color version of that same PC case. It's a very nice case, but it's also quite large and heavy. It'll take up more space, so make sure you have a place to put it.
