Looks great. Installed into wood box above stove and it sits flush.  Defintely buy before you build the box and account for any spacing we left about 18 on each side.  Since I had to plug in and then lift into box while powered but with fan disconnected, I didn’t take care to tape the electrical connectors as the unit is live...it was a rather shocking result. 

Once installed it’s very quiet when running.  Also make sure when removing film on filters to remove the screw and disassemble the filter to remove all of the film inside.
