Hi everyone, I need your thoughts here.
I'm trying to find a good place for the USB 3.0 front ports. A design I keep coming back to, in order for the USB ports to be on top with their wires running in the right direction toward the 20-pin header, requires making the case 0.2" (~5mm) deeper. The extra space brings the distance between the fan and GPU to 0.5" (12.7mm) allowing for an 11.5mm panel mount USB cable.
This would increase the volume from 16.7 to 17.0 liters. I'm cringing at the thought, but it is the ideal location, and solves another issue. It has the added benefit of adding access to the SATA ports on EATX 12"x10.7" motherboards. 8mm allows for Silverstone SST-CP11B-500 SATA cables for the two bottom-mounted drives.
I've considered on the front, above the fans, but with the trim ring shown in the OP, there really isn't room to shift the fans down and still make it look good. I don't want to disrupt the front.
Let me know what you think, good or bad. The power button will be a stainless steel E-Switch PV6F240SSG-301
(white) just beyond the USB ports on top. I've hidden the top and bottom flanges in these images for clarity, and illustrated an EATX 10.7" motherboard.
