Just got my Drop barebones keyboard. I got some Zilents V2 (https://zealpc.net/products/zilents) 67g switches, and Ducky Pudding keycaps. The keyboard looks & feels amazing !
The only catch with the Zilents switches, is the plastic feet need to be clipped.
I really like the high profile look where the switches aren't as exposed on my old keyboard that wasn't designed for modding. The aluminum frame is quite beefy, so it isn't going to move around allot. Hot swap switches mean that you save a lot of time because you don't need to solder.
The hot swap motherboard is designed for 3-hole switches, so the Gateron Aliaz Silent switches I used required removing 2 plastic pegs. The socket is recessed, so there were multiple times where the soft metal leads of my switches curled in the recess instead of going in the socket. Using the tweezers from my iFixit kit allowed me to uncurl them from the sides and still use them.
All in all, it's a solid keyboard which let me pick the parts I wanted. Since this is my first real custom keyboard, I am very happy with the process.
