The stock GPU I/O bracket does not allow for the Zotac 1080Ti MINI to fit inside the case with the HDPlex 400W power supply mounted internally above it. I thought of a solution that would shift the bracket 10mm and allow the GPU to slide towards the motherboard PCI-E slot. Originally, I modified the bracket using a Dremel tool and it turned out pretty well. However, I wanted more clearance between the GPU and the HDPlex power supply to allow for 180 degree GPU power cable adapters to fit, and to prevent the GPU from being suffocated at the top. Later, after collaborating with a friend that shared the same interest on NFC's Discord channel, we created a modified custom bracket that would provide a 14mm shift to allow for plenty of room.
