The author remixed this model.
Same as the original vertical nutcase, but with holes for screws in the front panels and respective m3-nut inlets in the side panels.
In the case of bulging (such as fron a stiff PCIE riser cable), the original front panels would jut out, affecting structural integrity and aesthetics. This remix fixes that problem. Still, I would not pick up the case by the sides, as these bulge inwards. Advise to use zipties to connect sides A and B together.
Requires at most 8 more m3 bolts. Used preferably with washers.
The only downside is that the front panels no longer have a uniform color scheme, due to the bolts/washers.
