I mounted the fridge properly, and made up the wiring for the USB charger that'll be mounted on the old fridge vent. I've also used caulk to take up some spaces that were left around the frame of the fridge. Not sure if I like that, to be honest, but it'll be easy enough to pull out if necessary. I also cut a laminate panel for the fridge door, so it's the same colour as the cabinets now, rather than being black. It's a lot better looking like that.
