The Innards of the Poseidon
Taking this keyboard apart is quite simple. There are three screws on the rear of the case that holds down the plastic that covers the premium green PCB the mechanical keys run on. The PCB is still being covered with a metal shield.
Most of the keys can be removed with a pair of flat-head screwdrivers or a key remover. The remainder of the keys need a bit more work to remove. Upon first inspection, many users would notice these are Kailh switches. It is worth to mention here that space bar has only one switch in the middle of it. We often see two switches for the space bar on mechanical keyboards.
