Thanks for all the help guys... I also see and respect both sides of the suggestions. As far as the B75 Board, I didn't want to limit myself in case in the future i will use this build as a workstation or I wanted to play with overclocking more. Also, the price difference between the B75 and the Z77 was minimal in my eyes. The Gigabyte Z77 board I chose was only $110.00 which is what really swayed me to go with it over the AsRock Extreme 4.
The RSV-L4500 was actually the case I was going to buy, but after looking at it more, It's quite a bit deeper then the 4000 and would have required some modifications to the spot I was going to put it. I was ok with this until I saw the RSV-R4000 was only $65 shipped. That's less then half the cost of the 4500. With the additional drive cage I plan to get I can still have 12 drives in there. With the way storage is going, now I could have 48TB of space minus parity so about 40TB. if that is not enough, I'm looking at the wrong class of case all together.
I feel confident in my parts for this build and I did want to slightly overkill it on the MB, CPU, SSD and RAM as with my current HTPC I cut corners on the SSD, RAM, and used an old gaming CPU and MB to save a minimal amount of money and I'm regretting it.
