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.Awesome! No compromise to the performance. Have you tried vertical stand? Or provide vented panel to the front?
