The most important clearance is around the vents where the compressor is located. You can get away with a vent cutout in the cabinet IF there is some space outside of that cabinet which equals 2". We don't ever recommend blocking the vents located on the fridge.
It's ok to have a slightly lower clearance above the fridge lid. It's not a bad idea to put reflectix or similar on the cabinet above the lid to keep the compartment insulated better. Less heat will get to the lid from outside sources.
The slide does add a tiny bit of height to the fridge, it's closer to 3/4". I'll try to get 100% accurate measurements uploaded from the team.
The CFX effect. ⠀

Bon Appetit! ⠀
