Homebuilt computer for 3D modelisation, rendering, animation and CGI

Ahh 3D graphic Modelling/Design Rig! Nice!

$5000 - $6000 will get you into a decent entry/mid range home built 3D workstation

CPU - go with a 6 Core, and unless you are an AMD fanatic, stick with Intel.

4930K Ivybridge E - Offers best bang for buck in a 6 core offering. 

The xx60K or xx70k offer marginal performance increases which you can attain by
simply over clocking if you really feel you need a boost.

Expect to spend $550 to $600

Motherboard -This is really really personal as to what you need to connect. If you are
 building your system, you are best off to research this yourself, to get a good feel for 
your platform. You will be looking for an LGA2011 X79 to match with the 4930k

Just at least make sure you get an x79 with 8 RAM slots. I like ASUS, and find them compatible for
 hackintosh'ing if ever inclined.

Expect to spend $200 to $400 for a decent board. 

Graphics Card - I would suggest either an Nvidia K4000 or Nvidia Titan based on your
 software choice. I know that the K4000 will perform much better in Maya than the Titan
 due to optimized workstation drivers.

The Titan may perform better in the other software choices although I would research this before you
purchased the Titan.

I would personally lean towards the K4000

Both are approximately the same price around $900-$1000

RAM - 32GB 8 Sticks of 4GB You can always upgrade as you go. 32GB should keep
 you going for a bit.

as for brand… I have found kingston to be very reliable. I use Kingston ECC RAM in
server/workstations simply for reliability. 

I suggest a Kingston HyperX at 1600mhz, low voltage… nothing above 1.7V This should give
 you good reliable RAM with fewer glitches in your renders. Nothing worse then rendering out
 a project with aberrations, and having to fix in post or re-render.

Expect to pay $350-$400 depending on liquidity of RAM prices.

SSD and Hard Drive - Get a nice 500GB or 1TB Samsung 840 EVO or Pro Very highly
 rated SSD on the market I have seen the 1TB version go for $500. With all your 
heavy 3D Software, (and certainly will find your self using Adobe CS at some point also)
 you will need the space and the speed. I would not get anything less than 500GB,
 you will fill it with programs fast enough. Western Digital Black Drives are nice for
 your big files and are pretty speedy for mechanical. Grab a couple 3 TB or 4 TB drives 
for your system. YOU WILL NOT WANT WDGREEN! The Western Digital Greens spin
 down too aggressively which is annoying and may be the cause of a reduced reliability.
 Western Digital or Hitachi. You do get what you pay for.

Expect to spend $700 -$1000++ just on your system drives

Power Supply - I like Seasonic. Powerful, quiet, efficient and dependable. I am sure 
there are other great power supplies out there, but I think most people agree at the 
very least that Seasonic makes good power supplies. 500 to 650W should be fine. 
A Gold should be fine. Platinum if you want fan less and silent.

Expect to spend $80 - $140 based on your needs/desires.

CPU Cooler - Noctua, Phanteks, and Thermalright make good air coolers. But most 
air coolers should be good enough, if you end up stuffing your case full of hard drives,
 add some more exhaust fans. The three brands I listed tend to be quiet and really
 efficient, and good enough for over clocking. 

Expect to spend $50 to $80

CASE - I like Antec based on price/performance/quality and style. Other cases may be
 nicer but a lot more pricier. Get a Case that will fit the number of hard drives you want,
 optical drives, other accessories. 

Expect to spend $50 - $140

OTHER - Optical Drives, flash card readers, Wireless Cards, Cables, additional case fans,
 thermal compound, tools etc…

If this is one of your first builds and you do not have much gear, budget according to need.

Monitors - at least 2, at minimum 1920x1200. More pixels more better. Try to get at
 least one decent reference monitor for decent colour.

The Dell UltraSharp 27" U2713H is very nice and relatively affordable for its level of quality.
Match it with another 27" monitor with the same 2560x1440 res and you will have a nice set up.
The second monitor does not need to be of the same level. Monoprice has some nice 27" monitors
at a good price.

Expect to spend $800 - $1200

Back up Hard Drives/NAS - Okay after spending countless hours designing, rendering, 
and iterating you do not want to loose your work. All Hard drives fail. All. It is just
 a matter of when. 3D modelling creates some huge files and you will likely want to 
keep multiple iterations of the same scenes. Stay away from seagate, I am sure 
there is science to back up my personal opinion, research if you like, but in 
server/workstation land we only use Western Digital Blacks/Reds and Hitatchi 
hard drives. Get matching pairs for backing up. If you RAID mirror, back up 
your mirror. If one drive in the pair goes, chances are the other will also. If you 
are serious about 3D Design, your digital files will be worth more than your 
entire system. If you do not have a NAS already, get one or build one. I build my
 own, but I have heard QNAP is affordable and decent. 

Expect to spend $350 to $600 for a decent 4 bay NAS barebones.

Also consider a UPS… Bigger the better… And test it.

So .. after that book…

If you go the mid/high end as I outlined, expect to spend anywhere from $4500 to $6000

Actually… this kind of looks like my next build… 

Good Luck!
