Here is my suggested build.
Case: Cooler Master HAF 932 Advanced
This case is a great for air or water cooling. It is a full atx case so it will pretty much fit anything. My second choice would be a Rosewill Thor V2
Motherboard: MSI Z87-GD65 Gaming LGA 1150
I have used this motherboard in a few other boards and never any complaints. Fast board with great capabilities especially when paired with a MSI video card. The onboard sound is great and the networking card is amazing. The OC Genie is also a major plus for amateur overclockers if you decide to go that route. All around amazing motherboard with a company that will stand behind its product.
CPU: Intel Core i5-4670K
This is always my first choice when going with an LGA 1150 build. Pretty much speaks for itself.
CPU Cooler: CORSAIR Hydro Series H80i
Even though it has a higher price tag than the H60. I much prefer the dual fans when it comes to water cooling especially when I want low temps throughout my case. Again if you plan to do some heavy overclocking go with the H100i for even better cooling.
Graphics: MSI Radeon R9 290X
I would only suggest if your budget allows it and you know how to properly overclock for the best performance.
OR
MSI GTX 780Ti
Again if you don't plan on over clocking your GPU too much the 780Ti is the way to go even though the 290X is faster and has a higher memory size and interface.
Memory: G.SKILL Ripjaws X Series 16GB (2 x 8GB)
Since the i5 series is only a dual channel and not a quad channel like the i7. Two sticks is all you need. I chose two 8GB because you will almost never need to size up from that. Plus if you do you aren't limited to going to 16GB but instead you can goto 32GB by just getting two more.
SSD: 2x SAMSUNG 840 EVO 120GB
HDD: WD BLACK SERIES 3TB
PSU: CORSAIR RM Series RM850 850W
This power supply will give you everything you need. Full Modular!
Cost with 290X: Subtotal $2,182.90
Cost with 780Ti: Subtotal $1,992.90
I know I didn't put a media drive but that is for you to choose. I don't know if you want to play blu-ray or not. But, I am sure you can handle that part yourself.
