Hi, I have the model 5i7RYH for one year ago, I want to know how is the correct way to dissassembly all parts to clean them. I'm living near to a cement factory and there are a lot of dusty, so I need to clean my NUC. Some instructions to make it?
There are two small screws that attach the NUC's board into the chassis. Remove these screws and very, very carefully pry up the board along the back edge. Again, very carefully; you don't want to break any of the plastic around the CIR interface on the front panel...
Disassembling your unit is not fully recommended by our end.
I found a video that could help you with this process (I don't think removing the cooler is necessary for cleaning purposes).

It has some tips on how to remove the Motherboard out of the chassis.
I hope this is helpful for you.
