Hi, I must finally add a few words from myself as I plan to buy version 3.0 as soon as possible. This will be my first SFF case even though I've been interested in this topic for several years. I apologize in advance for any mistakes - I use translator.
I will simply write down my ideas and opinions in points (random order):
1. I beg you not to change the overall dimensions of the case, at least not significantly. In my opinion, its proportions are perfect. I would like the volume to stay below 7 liters
2. In my opinion, you should mainly focus on redesigning the middle reinforcement and creating opportunities to install 2.5 slot GPUs. I think it is definitely worth sacrificing mounting space for SSDs considering how cheap and capacious Nvme drives have become.
3. Gen4 riser is a must even if the price will be higher
4. What do you guys think about moving the center brace even lower to make more room in the GPU area. I know there is a power connector between board and card, but maybe some clever cut in this brace would allow it
5. Since you have dropped support for SFX-L PSUs, why not move the PSU down to allow more room for cable management. That space at the bottom is wasted, the USB cable doesn't need that much, however, this will require a flatter power connector
6. Addition of a mounting space for 40mm fans on the top of the case. This does not seem complicated, but will allow for more possibilities
7. USB ports on the front panel should definitely stay.
8. I don't know what changes you had in mind for the vertical stand, but I think it shouldn't drastically change the look. Now it looks elegant and unique
9. Flow through cooler support - I know a lot of people are asking for this, but I agree with your opinion not to add ventilation to the back of the GPU. The case will then not look as good. Maybe a better idea would be to add a cutout like the one from the initial design of the 2.0 version for the back of the motherboard? And adding two cover plugs to the case - one solid, one perforated
10. Don't go overboard with making the case lighter. It's great that it's so solid. People who write to make it thinner and lighter do not realize that it is mostly the components that affect the weight.
I think that's it for now. If I remember something I will add it
