Alrighty, here's the system I have settled on:
https://secure.newegg.com/WishList/M...spx?ID=8208709

I'm pretty sure it won't blink at running 2 1920x1200 displays with 5 instances (4 on 1, 1 on the other)

I already have the drives (performance raid)

I am, however, unsure about the case and power supply. Any recommendations?
