Well you picked a quality case then. I wouldn't worry about being "original" because the best cases always attract lots of attention. You aren't going to find a beautiful, premium case that is under-marketed ever.
For my mini-itx gaming machine that I've currently got most of the parts for, I've got this case sitting in my room...
Mac Pro-esk. One of the biggest, and most flexible, mini-itx cases available. I absolutely love eeet, knew I was going to buy one immediately after seeing it. Though its not to everyone's taste.
I'm much more subtle in my approach to computer cases. I like steel, mesh, and / or brushed metal. I'm very demanding about the look of logos and I prefer no windows or LEDs.
I love my case, it's a mid size though

I'm dusting it now btw, don't heckle me
