The only real complaint I have had for my Keychron K4 has been the plastic case, so yesterday I decided NO MORE!
I took some aluminim stock plate I had left over from another unrelated project and trimmed it down, tapped and countersunk mounting holes, and give it a hand brushed look with some 80 grit sand paper.
So far it feels solid, and I love the diffuse reflections from the key illumination. Combining the open sandwich plate with low profile caps gives it a really cool "exploded" or raw look.
I also added some silicone rubber to some of the larger keys to tone the "ping" down and give them a heftier feel and sound.
I dont love the stock stabilizers that come with this board so they may be the next update. Switches and Firmware are already all custom.
