Ill try to summarize the whole story and get to the question quickly. So I have an Asus X79 Delux that is now 3 years old and I believe its starting to kick the bucket. The CPU I have is the 4930k and is only OC'd when I go do to large batch renders or render passes of various 3D work, which is maybe once in a few months, so its got a lot of mileage left on it. I noticed not many stores have a good selection (or any selection) of cheap VGA 2011 boards since 2011-3 seems to be the current gen. Because of this, I looked into the supermicro server boards with 2 CPU slots, and for $300-400 I could get a new one, and throw a second used 4930k in for about $150-200 which would massively help my render times and just overall seems like a better idea than spending $200-$300 on a used singe socket 2011 board. The only problem (that I see right now) is that Ive never installed Windows server, so I have some questions....
Example of the board: https://www.amazon.com/dp/B00BRF7DAC/ref=psdc_1048424_t1_B007EDAOMK
The Questions:
1) Should I go for windows server 2012 or 2016 (or other)?
2) Do I actually need a server rack, or will these boards fit in full size towers?
3) will my existing Components transfer (as in do servers need ram specific for server vs desktop)?
3.5) I have a custom liquid cooling loop, will the blocks fit over the socket, or do servers not use the same mounting pattern?
4) Will it run all or most of your typical windows programs? (Very specifically Maya, 3ds Max, Zbrush, Mari, Photoshop)
5) Assuming my 780ti can transfer, will I be able to play games on it? and will I be able to SLI it? (does Nvidia make GPU drivers that work for servers)
Thanks in advance, Ive built many computers, but Ive never done anything server related so im pretty much 100% new to servers. Any related server setup tutorials links etc would be greatly appreciated!
