Update 07/28/2015:
Hey everyone! Big update today.
Our manufacturer had produced a sample of our first prototype without any surface finishing, and we visited the factory to quickly test it out. While it worked, we weren't satisfied with its structural rigidity. This case is designed to hold loads (monitors, speakers,etc.), so it's absolutely important that it is physically strong.
Furthermore, our manufacturer said that having a varying-size hole pattern is too time-consuming for them to keep the same production price that we had agreed on. There was also mixed reception from the community regarding this design choice. We also received other feedback from the community, asking for the front IO to be moved to the front as well as for the design of a stand to hold the case vertically. Clearly, a redesign is in order.
After a lot of work, we updated the design to reflect the points mentioned above while keeping the same internal configuration (anything that it could hold before, it can hold now). The new design (renders updated in the OP) is stronger, has USB and audio plugs in the front, and employs a uniform yet unique hole pattern in the front to keep costs low. This new design has been submitted to the manufacturer, and they have made production prints for it. The second prototype is scheduled to begin manufacturing this week. We are also working on a case stand that also doubles as a slim ODD rack.
Despite this small setback in our timeline, we believe that it brought about a big improvement in the design. As always, we welcome any feedback regarding the design. Please don't hesitate to let us know what you think!
