I would love it if anyone can answer my questions
1. I've picked a water cooler from Cosair, will I need to add that extra 2 fans I included in my list?
2. Does my GPU go with my build? Or do I need a better on?
3. Does my power supply have enough slots for me to plug in all the parts I have on the list?

THANKS!

1. Have you consider air cooling for your CPU ? Some air coolers like the Phanteks PH-TC14PE or the Noctua NH-D14 cools better than the H100 from Corsair and are far more quieter. Plus, they are cheaper and you don't risk any liquid leaking into your computer.

2. Your GPU is OK. The performance are similar to the GTX 770 from NVIDIA. Though, I would have gone with NVIDIA instead.

3. Don't worry with that. A power supply comes with more cables than you'll ever need. In the case you miss one, you can find them very cheap on the web.

P.S. If I was you, I wouldn't go with Corsair for your PSU. They tend to break a lot. Instead, go with a widely trusted brand in power supplies such as XFX or Seasonic.

But I still need to know about question 1...
Do I need to buy seperate fans for the cooler?

No, the stock fans that come with the cooler are great. No need to invest in better fans.

One more question, I've looked at the power supply. Is it for sure that I can connect all my components into the slots?

Don't worry with that. You will still have avaible slots after connecting all these components.
