Ohh my jeebus, the info lol. Some of it is good, but some horribly wrong.
What is your budget?
What kind of games do you want to play?
Would you like to play with overclocking?
Below is some general info, but I would need to know a budget and use for recommendations.
First off, like some others said, ditch the watercooling. That is an enthusiast product, and this is very much a budget build computer. It would both add cost to the system, and you would gain literally no performance.
Secondly, as much as I loathe Intel as a company, do NOT get an AMD CPU. They are just leagues behind Intel at present. You will need one of the i5 series. Here is a list of CPUs that would work for you. The K at the end represents OverClockable CPU's. I recommend the i5-4690k or the i5-4590

Cases come with all the fans you will need, so don't bother buying extra ones. You might need one to control temps if you start OCing, but even then it is unlikely you will need it. For reference, I have a super power-hungry R9 280x that is factory OC'd, and then I OC'd it 10% on top of that. Also, my CPU is OC'd to a high, but stable temp... but I don't have any extra case fans. Temps are perfectly fine. Air temp: 72F, case temp: 76F. In general, extra case fans are more for aesthetics than anything else. That being said, if you want to have a blue fan, go for it. They are cheap, just think you really "need" one for cooling.
Wifi is perfectly fine for gaming as long as it meets your needs. I get 25ms with mine, and it is nice and stable. Wifi DOES NOT limit conenctions s[eed whatsoever! wtf people, lmao. Your local wifi connection is much faster than your conenction to the internet, and thus your wifi speed is a moot point. My god, the misinformation.
SSD's are a complete waste of money. They do help LOAD a game or your OS a few seconds faster initially, but they do not affect framerates or actual gameplay at all. They are far more expensive than a standard hard drive and are pure marketing hype. Get a nice 1-3tb WD or Hitachi drive and you are good to go.
The RAM you picked is fine, but since it is one stick, you won't get dual-channel performance. The difference is nominal in a majority of situations, so it isn't a big deal.
GPU: GT-740. FML lol. Dude... just. dude. you were getting extra fans, watercooling, and a super low-end gpu. GPU's you should consider: R9 270x (or 280x), an nvidia GTX 760, 770, 780, 960, 970. ebay is a GREAT place to get used gpus.
