So, I work with large C++ codes that can run on cluster machines, so I wanted a workstation that could compile that code quickly (you'd be surprised how long it takes) and also have some of the high performance hardware found in compute clusters.
It has worked quite well for that purpose, I'm very happy with how it compiles and runs code, so I think the right tradeoffs were made in terms of component choices. The fans also stay very quiet even under the load of compiling (to be fair, thats probably much less stressful than a benchmark would be).
Thanks to reddit's /u/haekuh for the parts list, I would have had a hard time selecting these on my own.
The biggest snag was the motherboard, which does not conform to the ATX spec. It is missing a hole in the middle, and the case has a solid pin that goes there. I had to use a Dremel to remove the pin. So watch out for that compatibility issue. Also the CPU coolers are a tight fit on the dual socket, I had to mount one of the fans in reverse to get it to fit. The GPU is a bit big, but if you remove two modular drive bays it fits okay.
Edit: Apparently the center pin does unscrew, so thats my mistake.
