Have you read the sidebar and rules? (Please do)

Gaming, possibly upgrading the GPU in a year and a half, so it will still be a good gaming PC for a while.

If gaming, what kind of performance are you looking for? (Screen resolution, FPS, game settings)

Max €750,- for the parts that I still need to buy

Provide any additional details you wish below.

I plan on building a new gaming PC using some of the newer components in my current PC.

I already own the GTX 970, Cooler Master 650W PSU, 250GB SSD and a 1TB HDD that's not on the list, so I'm not looking for suggestions on changing those parts. (the GTX970, PSU and SSD are 5 months old)

I'm not very experienced with building a PC but I think I'll manage. (and if I don't, I know people that can help me out)

So what I want to know is if this build is good as it is and if not, what alternatives you would suggest. Oh and also if I'm missing something/overlooked something.

As a side note, I'm considering buying a NZXT sleeved LED kit (red), if anyone has any suggestions on that front, please tell me!

Edit: Also, would I need to buy any seperate case fans?
