I do have the money to spend on this, my only hobbies are playing adult sports, which don't cost a lot of money, so I have a lot of disposable income. To put this in perspective, the last computer I built was in 2009 and I have an i7 3ghz Extreme edition with 16GB DDR3 1600 memory, SSDx4 RAID 0, and had originally put a GTX 280 in it. I think I spent 4 grand on that rig. The only thing I've done since then is upgrade the video card, and it still is faster than any computer I use elsewhere, including the brand new workstation class machine I have at work.
So, while I won't be using this machine to its 100% potential, it will get used, and it will last me for quite some time.
That said, I had originally chose the Air 540 case, but want to use the fan controller/display that comes with the Rampage V mobo. I think it would look a little stupid mounted vertically where you have to turn your head to read it. Other than that, I really liked what I saw on the 540. The H440 & 900D aren't cube shaped, and I wanted to do something different than the standard full towers I've had in the past. All he reviews I've read on the HAF XB Evo say it is an amazing case with extreme build quality, and it's only like $100. I figure I can order it, and if it's not what I want/expected, I can keep it for a test bench and choose a different case, but I need legitimate answers to the questions I raised in my original post.
Thanks
Edit, sorry 2009 was my I built the i975, 2011 was when I built the i7 6 core that I have now.
