There may be a second case that is done very soon after that does include the 5.25" bays, but with the vast majority of people not using them, I don't think they will be in it tbh. That may change, but they handicap liquid cooling options and I want the case to be an amazing option for both air cooling and liquid cooling. I hear your plea, we shall see. (dem rhymes)
They may actually be someone I approach for manufacturing, we shall see. But, personally I am not a big fan of the S-frame or D-frame cases. Some of them I do like, just not all of them. I really like the clean design and thing its much easier to work with as a modders as well, not that modders are a huge market but still something to think about. For instance I like some of the design aspects of the 303.
