I already own a Prime_E but I really love the layout and aesthetic of this board that I had to buy another one. This time around, the case is a 3d printed case from P3D which is translucent ruby red. The case also came with a FR4 plate and features a gasket-like mounting style.
As of now, the board has lubed T1 67g tactile switches with red stems and translucent smoky housing. I also added SIP sockets to each switch to allow for hot-swapping LEDs. Lastly, I also added some RGB strips at the bottom to take advantage of the translucent case.
Overall, I really dig the quality and feel of the 3d printed case. The T1 switches also sound and feel great on the FR4 plate.
