More stuff that just consumes a bunch of money.
Besides keyboards, I'm generally interested in the customization of ones deskspace- cool lamps, desks, mic stands, mats, chairs, etc etc. But even going as far as complete decoration.
Depending on the time of year, I'm also obsessed with EDC stuff, safety/straight razor shaving, and (some) streetwear and sneakers.
I really can pick the most expensive hobbies.
