2500€ (i know my build is above that-should be pushed down to 2,5k) Germany-Dont like shipping No preferred retailer Nescessary but added spereately Fluid simulation / Render No overclocking 24/7capability Appreciated No custom watercool loop but a closed one would be nice No New OS
Rendering/Editing/Work is done in NX 10.0, NX Nastran, Ansys 17.0, Blender Photoshop, After Effects, Illustrator (basically the whole cs 5 suite, upgrade to newer versions may happen
I have the same MB so maybe I can give some good info.
The CPU in your main build doesn't look like it can be ran in a dual CPU setup per Intels specs. You may want to look into if there is a workaround but Intel lists it as a 1 CPU per board max
ECC ram would be a great upgrade if your doing any type of serious work.
A closed loop is not necessary for this kind of application. Something like the noctua nh-u14s works great because it still provides the airflow you need for your ram. Remember these kinds of boards are setup for airflow in a certain direction and your case fans may not be able to deliver that unless you run them extremely fast.
The 900d is really expensive for what you get. If your looking for a cheaper solution the fractal xl fits this board well.
The last thing I can think of is make sure your PSU has leads that are long enough to power this board. Lots of PSUs have shorter cables and they wont work with this huge board(the power is along the top of the board). Either pick up extensions or make sure the manufacturer lists the specs for length. Also it needs to be able to power 2 CPUs lots of PSUs dont have 2 8pin cpu connectors.
