one thing i found out: 92mm rear fan is impossible, the case is too narrow. There's like 90mm space for rear fan, and the square screw holes looks like 71.5 mm , which is for 80mm fans.
Regarding Picopsu fitment, I'm worried some motherboard with 24pin layout too near the screw hole may intersect with power button(i.e. Asus A320i, B450i)
Have you considered making power button on the rear side?
According to the pictures posted, it looks like you cannot use the rear c14 connector with rear 80mm×2 fans. Also, i dont see the screw holes for them.
Technically yes, it will work. But those screw holes fixing itself to the chassis have no standards, so you might want to check them before you buy one.
