If you're looking for an easily customizable keyboard but don't want to build your own, Drop's aptly named CSTM line has you covered.

The CSTM80 is — as you might expect from the name — a mechanical keyboard that's designed to be customized. Just about everything, from the top plate to the case weight, can be swapped out, and Drop sells additional case plates, switch plates, keycaps, and case weights on its site. The keyboard comes with Gateron Brown Pro 3.0 or Milky Yellow KS3 switches and a polycarbonate top plate, as well as ABS keycaps with shine-through side legends. It's not designed to be a gaming keyboard, necessarily, but it does boast a 1,000 Hz polling rate and N-key rollover. And its TKL layout is the perfect size for most gamers.

The CSTM80 is available now for $149, but you can also pick up a barebones version (no keycaps, switches, or top case) for $99.

The CSTM80 is a wired mechanical gasket-mount keyboard with a tenkeyless (TKL) layout, which means it has a full function row, arrow keys, and a 3 by 2 navigation cluster. It also has an extra F13 function key, but no rotary knob.
