New build around i7-6850k: choosing components

I am planning a new build of a DAW PC. I have ordered a couple of key parts already. I will be reusing a few of the existing components from my current system.

CPU: i7-6850k
Already ordered.

Motherboard: MSI Gaming Pro Carbon
Already ordered. Ex-demo.

Case: Fractal Design Define R5
I haven't ordered it yet but I'm pretty much decided, unless anyone has any better suggestions.
UPDATE: Fractal Design Define R5 case now ordered.

RAM: 16GB 2400MHz 4x4GB
There are plenty of options for 2400MHz 4x4GB, but I will probably go with
Corsair Vengeance LPX 16GB (4x4GB), PC4-19200 (2400MHz) DDR4, 14-16-16-31
I don't even really need 16GB. My current system only has 6GB and never maxes out.

Drives: Multiple
I'll be adding a new 240GB SSD for the operating system (Windows 7), but others will be transfered from the old PC. Probably 6 in total (including 3 SSDs).

GPU: Matrox M9148 (existing)

PSU: Undecided

Cooler: Undecided
Needs to be quiet.

Comments welcome, especially on PSU and cooler.

Hi Kev,
Just bumping up this thread....
 
Regarding coolers, I have the NH-D14 which is very quiet, but it's huge. It should fit in a full ATX case (I believe your Fractal case is an ATX). The NH keeps things very cool (around 35 degrees). Another recommendation (from Fireberd/Jack) is Deepcool Captain 240EX and it's a water cooler (full kit).....if you're inclined to go that route. 
 
The EVGA SuperNOVA G2 850 80+ Gold has got good reviews, but it maybe a bit more wattage than you need....IDK?
Fully modular PSU should make things super easy with cable mgt./installation.
 
Best of luck mate with your upgrade and having extra RAM is always a good thing (even if you don't use it)....

I was considering that one until I watched a video about installing it. It's so huge in size that it gets in the way of other components. I'm not ruling out liquid coolers.

I would go for 2 x 8GB ram ... to leave room for future expansion (assuming the MB has 4 slots).

 
I probably won't need more. My current system only has 6GB and never maxes out. When I built it I had the intention of adding a further 6GB later, but the need never arose. I don't have Kontakt or anything similar that requires large amounts of RAM.
 
The new motherboard has 8 slots.

One problem that I have with the PSUs that I've seen is that they all seem to include so many outlets that would be unused in my system. For example, those PSUs in the EVGA range all have 4 separate GPU outlets. My graphics card doesn't even need to connect to the PSU. They all have a 2nd CPU outlet too. That a lot of waste in total.

The guy in this video has the Fractal Define R5 and has installed a NH-D15 (which is slightly bigger than the D14 and seems to be a few degrees cooler). As long as the case can house the cooler easily, it really shouldn't affect the other components (besides keeping them cool).
 
I have a Rosewill Thor 2 case and this being a full ATX, there's plenty of room in it. I'd imagine yours would be similar.
 
Anyway, just thought you might like to see this:
 
  

I eventually decided on the following parts:
PSU: BeQuiet Straight Power 10 700W
Cooler: BeQuiet Silent Loop 280mm
RAM: Corsair Dominator Platinum CMD16GX4M4A2666C15 16GB (4x4GB) DDR4
System drive: Samsung 850 Pro 256GB SSD

I've built it and got it working now. I still need to add more drives and finish installing software before it can be put to use and replace my existing rig. Unfortunately I need to leave my current setup intact for now, as I have been given an urgent project to finish. When it's all over I'll start a new thread and post a mini-review.

With socket 2011-3, you want to run the RAM in quad-channel for maximum performance.

 
Yes. That's why I opted for 4x4GB rather than 2X8GB.
