Awesome! No compromise to the performance. Have you tried vertical stand? Or provide vented panel to the front?
A vertical orientation would, unfortunately, make this case larger than 20L. We really like the vertical approach though as it takes up less room on a desk, but this would make more sense with a different layout. Also, a vented front panel wouldn't do much good as there isn't enough room for a proper fan in the front because of the power supply being in the way.
