My closet conversion was very rudimentary. I basically just pulled out the linens and shoved in the cigars. I put some weatherstripping around the doors to give them a better seal and added an active humidifier (had to have someone add an outlet). Not fancy but holds a few hundred boxes at humidity levels I'm happy with. It's in the middle of the house right across the hall from the thermostat, so I don't have any worries about temperature. I would like to upgrade and make it all fancy at some point, but this works so I've been spending money on other home remodeling projects instead.

Edit: To clarify, mine isn't a walk-in, though. Just a closetdor.
