A few suggestions
1. http://www.parvumsystems.com/product/m1-0-atx Just ordered this one myself, pure acrylic case, with many customization options, just hit them up!
2. https://www.in-win.com/en/gaming-chassis/509 Just announced really nice looking glass case, if you want to show off those Sli 1080
3. http://www.lian-li.com/en/dt_portfolio/pc-o8wbw/ Nice ATX case, (might be hard to work in) but makes your build a art piece.
4. http://www.ncix.com/detail/phanteks-enthoo-evolv-atx-aluminum-6c-130365.htm Lastly a cheaper glass case that won't break the bank! (Also comes in white and silver).
Thanks!
Warm regards,
Josh
