There will be a revised design feet that raise the case by about 15mm. It serves to provide decent air flow and also provides an identity for the design. Users can choose to remove the feet and install their own (common) feet (not included), but I think the new feet design should be quite nice in aesthetics and functionally. Will post some renders soon for feedback and comments.I like the fan choice. Negative pressure has worked well to cool all the components in these sandwich layouts and is in my opinion the most optimized use of space for air cooling. You don't even need a flipped PSU option like the T1 because you account for top and bottom fans. I would include options to offset the PSU with standoffs. I'd be interested in the 10mm removable feet and an accessory like a back hat that can cover cables in the back to make the case vertical. Me personally I'd likely sacrifice the front usb c and rout the power to the back hat to make it work for me but that's my own choice to make a design like this work. I would think others would flip it the other way to have cables running out the bottom.
Not to name those brands/cases, but baffles me that some of those with tiny rubber padded feet, that raise the case by about 3mm, but with bottom chassis fans at the same time...
