This system is one that I have wanted to build for a long time.
The CPU is an Intel Xeon x5690 but there is no option for this on PCPP. I opted to substitute for the next best thing in this list. The Fractal Design AIO cooler is hard to find in the US but I was able to have one shipped from the UK. This has been my Daily driver for about a year now. Currently considering a switch to 980ti Classifieds.
I have 3 1440p displays in nVidia surround with bezel correction set. It comes out to 7820x1440p. It works quite well with the exception of AA of course. There is a 4th display on top used as an accessory display
FYI, This case did need slight modification to fit an eATX board. Just be prepared.
