If I only knew how buddy, would've been did it.
Overkill is always better if plans will allow it, I plan on buying 3 1080p 144Hz monitors in the future so I wanted something with power and alot of vram. Also I'm enjoying using this to game on 1080p with two new features I'm using, one of its features called Virtual Super Resolution (VSR) "Get quality that rivals 4K, even on a 1080p display, designed to automatically re-render games at higher resolutions and dynamically rescale them for HD displays at higher quality and visual details."
Then there is Frame Rate Target Control (FRTC) "Fine-tune your graphics with real-time frame rate control limiting the target frame rate during gameplay, reducing GPU power consumption." I can keep games at a low 60FPS as my 1080p 40'' TV isn't the best 60Hz out there
At the time I was only going for a GTX 970 or GTX 980Ti so I went ahead and brought that PSU before the video card was changed to a R9 390X.
A R9 390x will work on a 600w PSU https://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards
but its working fine for now as I'm not over clocking anything, only time will tell if I will have to change out the PSU.
Okay, thanks for the answer I'm a noob when it comes to FreeNAS.

The Samsung SM951 is faster..
It shouldn't as the the case has a lot of ventilation on the sides, The 140MM fan I added to go in the back should be used to push more cold air into the case. With no 3.5 cage to make room for the bigger card, this added space gives more air flow as well. Besides the taking up of room in the case a HDD can add unneeded heat so SSD's only, one for the OS/one for games & documents. In my mind it should work out fine. If not there is always full out water cooling everything for more $$$.
Not sure if "too too" overkill, but I tried. I hope this is the case http://www.amazon.com/Lian-Li-PC-O5SX-Aluminum-Wall-Mountable/dp/B00UPIB2PO as it is what I based this on.
