Where's your HDD? Or are you running everything off SSD?
Everything is off my SSD pretty much have windows,antivirus,cpuz,firefox,Wow,D3, and Ccleaner and that's it. Still have 60 gigs free so I'm for sure not doing bad at all btw If I could change anything on my build I would have went with the regular shinobi the XL is a beast 35 pounds by it self other then that I love the case and how "clean" it looks.
Depending on the length of the 8pin cable that might not be so easy, I had to turn my PSU that way around for it to reach without over-straining the cable to connector solder points, it really felt like if I were to pull any harder something might snap.

Is this a computer you assembled yourself? There are... more than a few things I'd do different. Also, are you running 2x8GB modules and 2x4GB modules? I see no other way to achieve those 24GB of RAM (well, 3x8GB I guess).
