Computer advice needed

1.  just install W10 and later make some tweaks
2. I would install the OS and programs on a 500Gb drive... trying to do progs on a separate drive would be crazy IMO.  I have many plugs installed on the C drive and larger ones on my D drive.  Many Cake plugs are easiest to manage in the Cake directories.
3. Don't have a quick link for installation, but I recommend loading the latest W10 install on a USB drive.
If your sound interface is firewire, you may consider a mobo w built-in firewire... not so common anymore.
Is your PSU a 'quiet' one?
 
lots of stuff to consider on a new build and I don't have an hour to go into everything... look on the Windows 10 forum   http://www.tenforums.com/   and on Toms Hardware forum for specific answers.

Do you use sampled instruments? Do you use microphones in close proximity to the computer? These considerations will affect your component decisions.
 
There are "whisper quiet" cases and power supplies, and even water-cooled silent cases, but they're considerably more expensive and may be unnecessary. As long as your room is large enough that you can put some acoustical absorption between your mic and computer, and angle the mic so the computer is behind its dead zone, an ordinary desktop case/PSU will probably be fine.
 
Large amounts of RAM are only necessary if you use sampled virtual instruments. You'll only need 8GB for SONAR and audio-only or audio + software synthesizers, but if you're doing multiple large Kontakt libraries then 16GB should be considered the minimum. 32GB is not overkill if you do orchestral stuff.
 
An SSD is also a nice addition if you use sample libraries. Some folks like to use an SSD for the O/S, but that seems like a waste of money to me. I can wait 10 more seconds for Windows to boot, and even with an SSD you're still going to want to move your paging device to a conventional drive. But for sample libraries, it's well-worth the expense.
 
After you've compiled your parts list, I'd suggest comparing the cost to an equivalent system from Jim Roseberry. You might be surprised how little more it'll cost you for a DAW built by an expert. Unfortunately, I figured that out after ordering a custom build from another seller. Their price was only $150 less and I'll never be able to call them about audio-related issues. Even if I'd built it myself, as I've done with most of my past computers, the savings would have only been around $200.
 
 

Thanks for the responses very interesting stuff, keep them coming.
My knowledge is pretty good when it comes to putting computers together and I am mainly going to build this DAW system because my OLD system is out dated and cannot be change anymore, so you might say a personal project. I have had my OLD system for around 18years. Before I sold my Admin Network computer business I built it from scratch including a fully customizable mother board it took me nearly 12months to build and source all the parts that I needed but I ended up with a very powerful Beast that I could even put my own badge on and add more parts to (VERY HAPPY :) ).
Now I have fallen behind the eight ball with some of the techy stuff an just really after advice on what is the best way to install Win10, OH and yes I know about paging files, registries and windows searching and several programs running in the background etc... They are still part of the Old world systems back in the day.
Things have change a lot with hard drives cause we would always just install windows on C-drive and progams on E-drive (D-drive being for CD-Drive LOL), and then have a DATA Drive for all Documents etc...Back in the day it was always the more RAM you had the better. As I do use a lot of virtual instruments and hungry synths, I figure I would still go with 32gig apposed to 16gig RAM.
Interesting you should bring up about Hybrid drives cause I have a Seagate Momentus XT 750gig in the OLD PC which got updated to GEN2 when they first came out and it has and still is serving me well, and I was thinking of using Seagate ST2000DX001 Desktop SSHD 2TB for the sample libaries and Sonar folders ect... in the NEW DAW PC, basically because of it's size a cost. But I bought the WD Black 2tb for very very cheap around $50 Australian, so I was going to use this for all the Folder stuff within Sonar and the Windows Folders and also put the sample libraries on.
So now for a new work around, How does this sound?
C-Drive 500gig SSD : Windows 10 and programs including VST and plug ins - I already have a Samsung 750 EVO 500GB SSD which I can use
D-Drive Maybe get another 500gig SSD for the sample libraries this should be enough for what I use
E-Drive DATA - I already have the WD Black 2TB which I could put the Sonar Folders, Windows Folders and also the Pageing file onto
G and H-Drive would be my OLD Project files and some Short term Backups
Still waiting on a comment on the Mother Board  ASRock Z170 Extreme4
 
My Room is pretty big in size and has been fully acoustically treated, yes I use Mics and an Electric drum kit Roland TD30 and Bass Guitar and electric Guitar.
The PC Case has been custom Built by me just for this project, the power supply has been modified by me just for this project.
 
As far as checking with JIM yep I'm open for a quote but don't know if I would be able to get it sent to Australia.
 
As stated not really keen on water cool
Some theory facts - Water cooling apposed to direct fan 
Direct Fan- Cheaper than water Cool. As long as the proper Parts have been use and the system is looked after, and all the calculations are done for air flow and heat dispersion the fan can out last a water cooler (depending on how the water or fluid system is done)
Water cooling - Expensive, still has Fans for radiator, water pump can be very annoying and if not checked regularly can be a down fall and cost you a new rebuild. Water and or Fluid can go stale and may need refilling from time to time.
You can properly see in those statements, for water cooling, yes I have had a very very bad experience with water and fluid systems.
 
Parts List of items I already have:
Case
PSU
WD Black 2tb H/D
500gig SSD
Video: Gigabyte GEFORCE GT740
CPU Fan
 
Parts still to get:
CPU
M/B
RAM
Extra SSD's or Hard Drives
 
Again I would like to thank you all so much 

LOL yes Fanless video crad

Or consider no paging file.
 
RAM is faster than SSD.  If you have enough RAM, your PC doesn't need to swap, right?
 
IMHO, SSD is the way to roll now, except for backup and archiving drives.  The performance boost is whiplash inducing.
 
And the last time I checked, the Intel HD graphics was fanless and silent.  You only need a graphics accelerator if you plan to build a gaming rig.  The i7-6700K can support up to 3 monitors at 4k.

I'm also interested in the ASRock Z170 Extreme4 MB (helping out my nephew in building a gaming PC)....the reviews look good, but would like to know from actual users. I'll check around some PC/build forums as well and post back...

if you are worried about fan noise etc. the cheapest and most effective solution is to drill a hole in the wall, put the DAW in the other room, stick all USB and HDMI cables through the hole and fill the hole with foam or acoustic insulation ... unless it is a super silent all passive DAW, I would not even want it in the control room; it's just too annoying ...
