Hi and welcome to SPCR.
Will your apps make use of the 4 cores/ 8 threads of the i7?
I think so. I will be using a program called NinjaTrader.
For video, what are the four monitors' resolution and inputs? You could probably go with IGP + a cheap passive Gfx card.
Not sure of the resolution. I like to have the biggest text possible without distorting the image. 1 will be a 24inch Led. The other two 19 inch lcd. I will only be using 3 monitors to begin with. But wanted the option of adding 1 more later on. Which passive Gfx cards did you have in mind?
Any suggestions on a totally silent case given my dimensions?
