Looks like you have done a lot of work for this to be your first pass here as a build list; there is a lot more that looks right than wrong.
Regarding how is this system for your workflow? This PC would certainly do what you want it to do.
Regarding cooling, RAM and PSU will be fine.
Regarding is anything missing, yes a Blu-ray burner.
You did not state whether you want to A) build this and leave it alone for years, or B) make some upgrades in the future. If B), I only have a suggestion for your RAM choice. If A), I do have some suggested tweaks to how you spend your budget for this build.
You've heard it here before, but it is so true that Adobe has mastered the ability to tax just about all of your PC components (cpu, RAM, bus, drives, and video card) with Premiere Pro CS5 and above in order to make HD editing fast and fun. This makes balance important and in some ways a system is only as strong as its weakest link.
Your current plans strike me as:
CPU = A+, RAM = A+++ on paper, but possibly a bad idea, Drives = B-, GPU = A-.
My only strong suggestion is to go for 32GB of 1600 RAM. You want to do a moderately strong OC on the CPU and the memory controller of the 3930k is not strong enough to pull this off.
Minor suggestions: A) more drives - go for at least one 2x1TB RAID 0 array for media, projects, and scratch (adding one more drive). B) SSD for boot - for spending as much as you are here, I think your build deserves a 128GB SSD for the boot/OS drive - no this will not help after Premiere Pro has started and you are editing, but it will make the PC faster for lots of other things that most users do.
Thanks for the reply. Some follow up questions:
So you think with the 3930, I'd get better performance/stability with only 32gb of the crucial RAM?
On the SSD, I've gone back and forth. I also use the boot drive for storage, so I was thinking the 1tb would come in handy, but I guess I can always pop in another HD if I need it. In that case, it would most likely be a Crucial M4 that I'd use. Sound correct?
On the 2x1TB RAID 0, would there be a significant performance benefit? I've gone back and forth about this too, and thought about RAID0 for media and projects, but in allowing for the time for disciplined backup, I haven't determined the cost/benefit. Thoughts?
In answer to your question about my plans for the system, it's most likely A, build it and use it for the next couple of years as is, maybe adding a BMD card at some point.
Also, forgot to list it, but here's the BR drive I'm planning on.
