Trimmed as much width as possible and reversed the side the riser mounts onto to gain even more space. It now takes up less space than the riser cable itself. Supports are now needed against the riser mounting area.

I'm using this bracket to fit my XFX MERC 319 in the original Evolv Shift. I also had to make these accommodations to make it fit:

1. 180deg ATX 8pin connectors. (You'll need to buy this one twice, to get a single pair of connectors in the correct orientation, leaving you with another pair of useless connectors.)
2. Either a CPU fan or a radiator that can be jammed in the space next to the motherboard where a fan would normally sit, with a slim fan on the outside of the frame. I'm using the EK-AIO 120 RGB, and the rad fits with enough convincing. I also have yet to test with the panel on, but I suspect I may need to buy a modded panel with cutouts.
3. An extension for the ATX 8pin CPU connector is also recommended, depending on how long your PSU's provided one is. This is so you have enough length to route the cable in such a way that doesn't restrict airflow through the radiator.

I'm currently waiting on the power connectors, then I'll post photos of the final setup. I might also throw in a TPU pad or some kind of clip for the GPU to sit on, since it's so damn long it basically reaches the bottom of the case, anyways.

Not tested with the Evolv Shift 2.
