With two intake fans and the CPU / GPU intakes, & a single exhaust fan; it would definitely be a Positive Pressure setup, which is good...
The entire front section of the inner chassis frame would need to be redesigned, if it was perforations, those are pricey...
The height of the chassis right now is 246mm, which also includes the thickness of the bottom, the inner top flange, & the top plate itself...
So for dual 120x25mm fans up front, the chassis would also need to be increased in height...
And the fans would take away from room for longer GPUs (most of the current line-up of ITX-sized GPUs are longer than the ITX motherboard & come close to the inside of the front inner chassis wall...
At this point, we might as well increase width slightly (5mm) to ensure capability with the Noctua NH-L12S CPU cooler...
A benefit of all this would be easier use of a SFX-L PSU (not fan or SSD on the floor of the chassis), giving options for 700w & 800w PSUs (and for that 450w fanless PSU)...
Not saying I wouldn't mind seeing such a chassis as a follow-up to Fire's MI-6...!
Be great for ensuring that a Vega Nano stays somewhat cool...!
